Abstract
具有下式的新颖化合物(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯在杀虫方面具有高度活性。
Description
本发明涉及(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯、其制造方法、及其用作一种杀虫剂。
人们已公开了具有杀虫特性的2,2-二甲基-3-(2,2-二氯乙烯基)环丙羧酸酯与多氟化的苄基醇类的酯(这方面,可参看德国专利说明书2658074及英国专利说明书1567820)。五氟苄基酯与由等份量的2,3,5,6-四氟苄基酯和3,5,6-三氟苄基酯组成的混合物比较,显示出优良的杀虫作用,它只需使用十五之一的份量即可于同一时间内将苍蝇杀灭。同样地,单独使用四氟苄基酯也有良好的杀虫作用。
而且人们知道(-)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸五氟苄基酯乃非常适合于杀灭家居,卫生环境及产品储存处的害虫。(见Behrenz,Naumann 1982)。而在同一公开上,人们亦可知道这个活性化合物对哺乳动物有颇高的毒性(老鼠的口服半数致死量以毫克/公斤计为90-105)。相应的2,3,5,6-四氟苄基酯的顺式/反式混合物甚至具有更高的毒性(雄鼠的口服半数致死量以毫克/公斤计为10-25)。不过,如用合适的低剂量就无需禁止这些有毒活性化合物在家居,卫生环境和产品储存处作为保护剂来使用。但是,研究者的任务是要寻找更多非毒性物质;它们在对于害虫的有效剂量方面和对于人类及动物的毒性作用方面有着更大的差距,即是说它们具有非常良好的治疗指数,因而使用这些化合物的安全性增加。
新颖的具有式(Ⅰ)的(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯已被发现
式(1)的(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯)可由以下之一的方法获得:
a)在20至100℃之间的温度下,将式(Ⅱ)的(+)-1R-反式-二氯苯醚菊酯酸氯化物(permethrin acid chloride)
与式(Ⅲ)的2,3,5,6-四氟苄基醇反应,或
b)将式(Ⅳ)的(+)1R-反式-二氯苯醚菊酯酸的盐,
其中X表示可移去的阴离子基团。
由于(新的(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯对哺乳类动物具有非常低的毒性,并有高活性(雄鼠的口服半数致死量以毫克/公斤计超过5000),而显示出非常有利的治疗指数。
因此,它对哺乳类动物的毒性比顺式/反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸四氟苄基酯的毒性低250倍以上,比(-)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸五氟苄基酯的毒性低50倍。就其本身而言,假若所要求保护的新的化合物也失去防治害虫的活性至相同的程度,这并不那么令人惊奇。然而,事实并非如此。反而,毒性较高的顺式/反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸四氟苄基酯的生物学作用低于毒性较低的本发明的(+)-1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸四氟苄基酯。与(-)-1R-反-3-(2,2-二氯乙烯基)-环丙羧酸五氟苄基酯比较,式(Ⅰ)的(+)-1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸四氟苄基酯在相同或略为较高的剂量下具有类似的杀虫作用。
因此,新的(+)-1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯的提供代表了本技术水平的一个大进展。
制备(+)1R-反式-2,2-二甲基-3-(2,2-二氯乙烯基)-环丙羧酸2,3,5,6-四氟苄基酯可以下列的反应式表示。
在变更的方法a)中,从Pesticide Science 1974,796中已知的(+)-1R-反式-二氯苯醚菊酯酸氯化物,在20至100℃之间的温度下,在有或没有溶剂的存在下,若适当的话,在酸结合剂的存在下,与从J.Chem.Soc.C.1968,1575中已知的2,3,5,5-四氟苄基醇反应。
在该变更的方法中,最好在30至80℃之间的温度下,在没有溶剂及酸结合剂的存在下,使组分反应,让所产生的挥发性组分(最好是氯化氢气体)排出,随后反应产物最好经蒸馏处理,在变更方法a)中的起始组分最好采用等摩份分量。
在变更的方法b)中,(+)1R-反式-二氯苯醚菊酯酸的盐(特别是碱金属盐)最好与2,3,5,6-四氟苄基氯,其苄基溴或其甲苯磺酸盐反应,同样最好以等摩尔份量。在酯化作用的意义上,类似于Synthesis 1985,805中的过程,并在有或没有烷基化催化剂的存在下进行反应。
在式(Ⅴ)的起始化合物中,X最好表示囟素,特别是氯或溴,或表示甲苯磺酸盐基团(对-甲苯磺酸的基团)。
变更的方法b)的反应最好在溶剂中,特别是在对反应具惰性的极性有机溶剂中进行。可以溶剂:乙腈,丙酮和二甲基甲酰胺为例。
在这里,所产生的式(Ⅰ)的化合物的最好处理也是蒸馏。
变更的a)和b)两方法最好是在大气压下进行。
本发明的活性化合物适合于杀灭动物害虫,特别是昆虫;这些害虫出现在家居中,或作为卫生环境或产品储存处的害虫出现。它对一般敏感的和/或抗药性害虫都具有活性,并能防治其全部或某些发育阶段。
上述害虫包括:
缨尾目,例如,西洋衣鱼。
革翅目,例如,欧洲球螋。
等翅目,例如,黄胸散白蚁。
异翅亚目,例如,臭虫,Rhodnius prolixus,及Triatoma infestans,

双翅目,例如Aeedes aegypti,Anopheles spp.,Culex Spp.,家蝇,Fannia spp.,黑颊丽蝇,丝光绿蝇,带金果蝇,Stomoxys spp.,及Tabanus Spp.
蚤目,例如东方鼠蚤及Ceratophyllus Spp.
本发明的活性化合物可以单独施用或与其他杀虫剂例如磷酸酯类,氨基甲酸酯,拟除虫菊酯或芳基吡唑混合施用。
当与其他杀虫剂混合时,可以下列可混合的组分为例:
磷酸酯类:敌敌畏(DDVP),杀螟松、马拉硫磷、氯蜱硫磷、地亚农及methyl pyrimiphos。
氨基甲酸酯:残杀威、呋喃丹、西维因、及苯噁威。
拟除虫菊酯:Cyfluthrin,似虫菊、丙烯菊酯、vaporthrin,terallethrin,苄呋菊酯esbiol,腈二氯苯醚菊酯、alphamethrin,decis及二氯苯醚菊酯。
