Opfindelsen angår hidtil ukendte bis-(3,5-dicarboxylsy-re)-estere af tetrahydropyraner og piperidiner med herbicid aktivitet.
5 I litteraturen er beskrevet visse bis-(2,6-trifluorme-thyl)-3,5-dicarboxylsyreestere af tetrahydropyraner og piperidiner. Således har Baldev Singh et al., publiceret en rapport om nogle undersøgelser i The Journal of Heterocyclic Chemistry, bind 17, 1109 (1980), hvori de 10 beskriver reaktionen mellem ethyl-4,4,4-trifluoraceto-acetat og acrylaldehyder og vandig ammoniak i ethanol. De opdagede, at der ved en sådan reaktion, der tidligere er rapporteret af Balicki et al., Chem. Abstracts, bind 82, 72739P (1975), fremkom diethyl-4-aryl-2,6-dihydroxy-2,6-15 bis-(trifluormethyl)-3,5-piperidindicarboxylater i stedet for diethyl-4-aryl-l,4-dihydro-2,6-bis-(trifluormethyl)-3,5-pyridindicarboxylater. Det blev også angivet, at ste-reoisomere af de rapporterede piperidindicarboxylater var af usikker natur. Der blev ikke angivet nogen anvendelse 20 for forbindelserne.
The Journal of Organic Chemistry, bind 30, side 3237-3239, september 1965, indeholder en rapport af Dey et al., om syntesen af fluorholdige tetrahydropyraner. Ved 25 reaktionen mellem ethyl-trifluoracetoacetat og forskelli ge alifatiske og aromatiske aldehyder under anvendelse af de sædvanlige Knoevenagel-betingelser fremkom der forskellige 4-substituerede forbindelser. Kondensation af ethyl-trifluoracetoacetat med aldehyder blev gennemført i 30 nærværelse af både piperidin og kaliumfluorid under anvendelse af to forskellige metoder, til tilvejebringelse af de forbindelser, der har interesse. Man rapporterede forbindelser, der i 4-stillingen på 3,5-dicarbethoxy-2,6-dihydroxy-2,6-bis-(trifluormethyl)-tetrahydropyran-mole-35 kylet var substitueret med methyl, ethyl, phenyl, p- fluorphenyl og p-methoxyphenyl. Der blev ikke angivet nogen anvendelse for forbindelsen, og ej heller er der be-

2 skrevet substituenter i 4-stillingen omfattende alkyl med -forgrenet kæde.
I USA patentskrift nr. 3 700 695 til Carr et al., er der 5 beskrevet forbindelser, der har den følgende almene formel 10 H2f R R R ί - C - C - C —1 I ' '
R R R
n s 15 hvor n er mellem 0 og 1, hvorved et af radikalerne R er valgt blandt fluor, alkyl, cycloalkyl, aryl, perfluoral-kyl, perfluorcycloalkyl og perfluoraryl, hvorved et andet af radikalerne R kan være valgt blandt alkyl og perfluor-alkyl, hvorved de resterende radikaler R er valgt blandt 20 hydrogen og fluor, med det forbehold, at mindst et af radikalerne R indeholder fluor eller er fluor, s er et tal mellem 1 og 3 inklusive, og M er valgt blandt fluor, chlor, brom, iod, cyano, alkylcarbonyloxy, arylcarbonyl-oxy, cycloalkylcarbonyloxy, alkylsulfonyloxy, cycloalkyl-25 sulfonyloxy, arylsulfonyloxy, phosphinylidyntrioxy, phos-phinidyntrioxy, alkoxyphosphinidendioxy, dialkoxyphos-phinoxy, aryloxyphosphinidendioxy, diaryloxyphosphinoxy, alkylphosphinylidendioxy, arylphosphinylendioxy, sulfonyl og sulfinyl. Fremstillingen af disse forbindelser og an-30 vendelserne deraf til forbedring af transparensen af formstoffilm og som herbicider er også beskrevet. Som det fremgår af den før angivne formel forekommer der i disse forbindelser fluorsubstitution på ringen direkte, eller ringen kan være substitueret med perfluoralkyl-radikaler.
35 Det er rapporteret, at visse af disse forbindelser har herbicid aktivitet, mens størstedelen af forbindelserne blev anvendt som transparensfrembringende midler i film 3
DK 164498 B
af polyvinylchlorid. De i herbicid henseende aktive forbindelser var generelt ringsubstituerede, fluorholdige forbindelser, der har et carbonyloxy- eller sulfonyloxy-radikal i 2-stillingen i pyranringen. Man har iagttaget 5 herbicid aktivitet før spiringen af sådanne forbindelser hvad angår ris, hirse og agurk.
Den foreliggende opfindelse angår hidtil ukendte 3,5-dicarboxylsyreestere af 2,6-bis-(fluoralkyl)-tetrahydro-10 pyraner og -piperidiner med den i krav 1 angivne almene formel. Disse forbindelser har herbicid aktivitet.
Forbindelser, i hvilke er et forgrenet Cg_^~alkyl, er særlig foretrukne. Typiske eksempler på radikaler af den-15 ne art er 1-methylethyl, 2-methylpropyl og 1-ethylpropyl.
Et typisk radikal af typen C^-C^-alkyl er ethyl.
20 Typiske Rg radikaler af typen fluoralkyl omfatter trifluormethyl-, difluormethyl-, monofluormethyl- og pen-tafluorethyl-radikaler.
Piperidinforbindelserne ifølge opfindelsen kan forekomme 25 i to stereo-isomere former, som generelt kaldes de "trans-" og de "cis-" isomere. I henhold til opfindelsen har man iagttaget den herbicide anvendelighed af de før beskrevne piperidinforbindelser i begge isomere former og i blanding. Den her foreliggende beskrivelse med krav om-30 fatter begge isomere former og blandinger deraf.
Som det er bekræftet ved Rontgenstrålekrystallografi af enkeltkrystaller er de isomere strukturer repræsenteret ved den formel, hvori (a) er cis og (b) er trans.

Pyranen fremstilles således ved reaktion mellem et aldehyd og en passende 3-ketoester i nærværelse af enten pi-20 peridin eller kaliumfluorid i katalytiske mængder. Når reaktionen mellem aldehydet og 3-ketoesteren gennemføres i nærværelse af vandig ammoniak, tilvejebringes der pipe-ridin-forbindelser i henhold til den tekniske lære, der er fremsat af Singh et al., hvortil der er henvist i det 25 foregående, i henhold til følgende reaktionsskema:

Som før anført har det vist sig, at forbindelserne ifølge · opfindelsen er effektive som herbicider før spiringen. Tabellerne I og II sammenfatter resultaterne af prøver, der er gennemført for at bestemme den herbicide aktivitet 5 før spiringen af forbindelserne ifølge opfindelsen.
Man gennemfører prøverne før spiringen på følgende måde:
En god kvalitet af overfladejord indføres i aluminiumskå-10 le og komprimeres til en dybde på 0,95 til 1,27 cm fra toppen af skålen. På toppen af jorden indfører man et forudbestemt antal frø eller vegetative formeringsorganer af forskellige plantearter. Den mængde jord, der kræves til at fylde skålene op til niveau efter såning eller 15 tilførsel af vegetative formeringsorganer, indvejes i en skål. En kendt mængde af den aktive bestanddel, indført i et solvent eller i form af en suspension af et befugte-ligt pulver, blandes grundigt med jorden og anvendes som et dæklag til allerede tilberedte skåle. Efter behandling 20 bliver skålene flyttet til en drivhusbænk, hvor de vandes nedefra efter behov til frembringelse af tilstrækkelig fugtighed til spiring og vækst.
Ca. 2-3 uger efter såning og behandling iagttages plan-25 terne, og resultaterne registreres. I den følgende tabel III er disse resultater sammenstillet. Den herbicide karaktergivning hviler på en fikseret skala, der er baseret på den procentiske beskadigelse af hver planteart. Karaktergivningen er defineret på følgende måde: 30
Karakterer Inhibering givning 0-24 0 35 25-49 1 50 - 74 2 75 - 100 3 13

Forbindelserne ifølge opfindelsen kan inkorporeres i herbicide blandinger under anvendelse af alment kendt teknik. Det forventes, at de herbicide blandinger ifølge opfindelsen, herunder koncentrater, der kræver fortynding 5 før anvendelse, i et typisk tilfælde indeholder mindst en aktiv bestanddel og et adjuvans i flydende eller fast form. Sådanne blandinger fremstilles ved at blande den aktive bestanddel med et adjuvans, herunder fortyndingsmidler, strækkemidler, bærere og konditioneringsmidler, 10 til tilvejebringelse af blandinger i form af findelte, partikelformede, faste stoffer, granulater, tabletter, opløsninger, dispersioner eller emulsioner. Den aktive bestanddel kan således anvendes med et adjuvans, såsom et findelt, fast stof, en væske af organisk oprindelse, 15 vand, et befugtningsmiddel, et dispergeringsmiddel, et emulgeringsmiddel eller enhver passende kombination af disse.
Det antages, at blandingen, som indeholder en forbindelse 20 ifølge opfindelsen, især væsker og befugtelige pulvere, fortrinsvis som konditioneringsmiddel, bør indeholde et eller flere overfladeaktive midler i mængder, der er tilstrækkelige til at gøre en given blanding let disperger-bar i vand eller olie. Inkorporeringen af et overfladeak-25 tivt middel i blandingerne forbedrer i høj grad deres effektivitet. Betegnelsen "overfladeaktivt middel" skal i denne beskrivelse med krav omfatte befugtningsmidler, dispergeringsmidler, suspenderingsmidler og emulgerings-midler. Man kan anvende anioniske, kationiske eller ikke-30 ionogene midler med lige stor lethed.
Typiske befugtningsmidler er alkyl-benzen- og alkyl-na-phthalen-sulfonater, sulfaterede fedtalkoholer, aminer eller sure amider, langkædede sure estere af natriumiso-35 thionat, estere af natriumsulfosuccinat, sulfaterede eller sulfonerede fedtsyreestere, jordolie-sulfonater, sulfonerede vegetabilske olier, ditertiære acetyleniske gly-
DK 164498 B
17 coler, polyoxyethylen-derivater af alkylphenoler (især isooctylphenyl og nonylphenol) og polyoxyethylen-derivater af de mono-(højere fedtsyre)-estere af hexitol-anhy-drider (f.eks. sorbitan). Foretrukne dispergeringsmidler 5 er methylcellulose, polyvinylalkohol, natrium-ligninsul-fonater, polymere alkyl-naphthalen-sulfonater, natriumna-phthalen-sulfonater og polymethylen-bisnaphthalen-sulfo-nat.
10 Befugtelige pulvere er vand-dispergerbare blandinger, der indeholder en eller flere aktive bestanddele, et indifferent, fast strækkemiddel og et eller flere befugtnings-og dispergeringsmidler. De indifferente, faste strække-midler er sædvanligvis af mineralsk oprindelse, såsom de 15 naturlige lerarter, diatomejord og syntetiske mineraler afledt af silica og lignende. Eksempler på sådanne stræk-kemidler omfatter kaolinitter, attapulgitler og syntetisk magnesiumsilicat. De befugtelige pulverblandinger ifølge opfindelsen indeholder sædvanligvis mellem ca. 0,5 og 80 20 dele (fortrinsvis så meget som muligt op til 80 dele) aktiv bestanddel, fra ca. 0,25 til 25 dele (fortrinsvis 1-15 dele) befugtningsmiddel, fra ca. 0,25 til 25 dele (fortrinsvis 1,0-15 dele) dispergeringsmiddel og mellem 5 og ca. 95 dele (fortrinsvis 5-50 dele) indifferent, fast 25 strækkemiddel, hvorved alle dele er på vægtbasis i forhold til den totale blanding. Om nødvendigt kan fra. ca.
0,1 til 2,0 dele af det faste, indifferente strækkemiddel erstattes med en korrosionsinhibitor eller et skumdæmpningsmiddel eller begge.
30
Andre formuleringer omfatter pudderkoncentrater omfattende fra 0,1 til 60 vægt-% af den aktive bestanddel på et passende strækkemiddel; disse puddere kan være fortyndet med henblik på anvendelse i koncentrationer indenfor om-35 rådet mellem ca. 0,1-10 vægt-%.

Man kan fremstille vandige suspensioner eller emulsioner ved omrøring af en vandig blanding af en vanduopløselig aktiv bestanddel, et passende ikke vandigt solvent dertil, og et emulgeringsmiddel, indtil der fremkommer ens-5 artethed, og ved påfølgende homogenisering til dannelse af en stabil emulsion af meget findelte partikler. Den resulterende koncentrerede vandige suspension er karakteriseret ved sin ekstremt lille partikelstørrelse, således at dækningen er meget ensartet, når der fortyndes og 10 sprøjtes. Passende koncentrationer af disse formuleringer indeholder fra ca. 0,1-60% (fortrinsvis så højt som muligt) på vægtbasis af aktiv bestanddel, hvorved den øvre grænse er bestemt ved opløselighedsgrænsen af aktiv bestanddel i solventet.
15
Koncentrater er sædvanligvis opløsninger af aktiv bestanddel i med vand ublandbare eller partielt med vand ublandbare solventer, sammen med et overfladeaktivt middel. Passende solventer til den aktive bestanddel ifølge 20 opfindelsen omfatter dimethylformamid, dimethylsulfoxid, N-methylpyrrolidon, carbonhydrider og med vand ublandbare ethere, estere eller ketoner. Man kan imidlertid formulere andre flydende koncentrater med høj styrke ved at opløse den aktive bestanddel i et solvent og ved derpå at 25 fortynde, f.eks. med kerosin, til sprøjtekoncentration.
Den her omhandlede koncentratblanding indeholder sædvanligvis mellem ca. 0,1 og 95 dele (fortrinsvis 5-60 dele) aktive bestanddel, ca. 0,25-50 dele (fortrinsvis 1-25 de-30 le) overfladeaktivt middel og om nødvendigt ca. 4 til 94 dele solvent, hvorved alle dele er på vægtbasis i forhold til den totale vægt af emulgerbar olie.
Granulater er i fysisk henseende stabile, partikelformede 35 blandinger, der omfatter aktiv bestanddel, som adhærerer til eller er fordelt gennem en basismatrix af indifferent, findelt, partikelformet strækkemiddel. For at un-
DK 164498 B
19 derstøtte udludning af den aktive bestanddel fra det partikelformede materiale, kan der i blandingen foreligge et overfladeaktivt middel, såsom dem, der er anført i det foregående. Naturlige lerarter, pyrophylitter, illit og 5 vermiculit er eksempler på anvendelige kategorier af partikelformede, mineralske strækkemidler. De foretrukne strækkemidler er de porøse, absorberende, forud tildannede partikler, såsom forud tildannet og sigtet partikelformet attapulgit eller varmeekspanderet, partikelformet 10 vermiculit og de findelte lerarter, såsom kaolinler, hy-dratiseret attapulgit eller bentonitler. Disse strækkemidler sprøjtes eller blandes med den aktive bestanddel til dannelse af de herbicide granulater.
15 Den granulære blanding, som indeholder en forbindelse ifølge opfindelsen, kan indeholde mellem ca. 0,1 og ca.
30 vægtdele aktiv bestanddel pr. 100 vægtdele ler og 0 til ca. 5 vægtdele overfladeaktivt middel pr. 100 vægtdele partikelformet ler.
20
Blandingen kan også indeholde andre additiver, f.eks. gødningsstoffer, andre herbicider, andre pesticider, sikringsmidler og lignende materialer, der anvendes som ad-juvanser, eller i kombination med ethvert af de før an- 25 givne adjuvanser. Kemikalier, der anvendelige i kombina tion med de aktive bestanddele ifølge opfindelsen omfatter triaziner, urinstoffer, carbamater, acetamider, acet-anidlider, uraciler, eddikesyre- eller phenolderivater, thiolcarbamater, triazoler, benzoesyrer, nitriler, bis-30 phenyl-ethere og lignende, såsom:
