Abstract

NEW MATERIAL:The titled compound expressed by formula I [R1 is NO2 when R2 is H, and NO2 or formula II (R3 is H, methyl or ethyl) when R2 is NO2].
EXAMPLE: 4-(3,5-Dichloropyridyl-2-oxy)-1,2-dinitrobenzene.
USE: A herbicide with low phytotoxicity to rice plants. The content of the derivative is preferably 2W10wt.% in a granule, 20W30wt% in a wettable powder and 10W 50wt% in an emulsion.
PROCESS: 3,5-Dichloro-2-bromopyridine is reacted with m-nitrophenol in the presence of a deacidifying agent in the presence or absence of a polar solvent at 140W150°C for 2W4hr to give the compound of formula I (R1 is NO2 and R2 is H). The resulted compound is then nitrated with a mixed acid at 50W60°C for 1W3hr to afford the compound of formula I (R1 and R2 are NO2) which is 4(3,5-dichloropyridyl-2- oxy)-1,2-dinitrobenzene.
