Abstract
Description
本发明是关于新的取代的苯乙酸衍生物的制备方法。
在英国专利2161163号中揭示了下式化合物具有杀虫活性:
其中R1是卤素或烷基;R5是氢或卤素;R3是氢或甲基;R4是氢、低级烷基、各种链烯基、炔基和取代的甲基、以及乙酰基和甲氧羰基;R2是低级烷基。在该专利中,仅仅揭示了那些R2是异丙基的化合物。现在,我们发现R2是叔烷基的类似结构化合物具有显著有益的特性。尤其是在我们将这些化合物与已有文献中R2为异丙基的类似物作比较时,表明本发明的化合物增进了抗某些害虫的活性。
我们还发现当本发明的化合物与英国专利2161163的异丙基类似物相比较时,例如在土壤中有较高的稳定性。这个稳定性特别有利于灭除存在于土壤中的害虫,如条叶甲属类。
因而,按照本发明提供了通式Ⅰ的苯乙酸衍生物:
其中
R1是被一个或多个相同或不同基团任意取代的苯基,这些取代基团选自卤素、羟基、C1-4-烷基、卤代-C1-4烷基、C3-6-环烷基、卤代-C3-6-环烷基、C1-6烷氧基(被卤素、C1-4烷氧基、C1-4-烷硫基、C1-4-烷氨基或二-C1-4烷氨基任意取代)、C2-6-炔氧基、卤代-C2-6-炔氧基、C2-6-链烯氧基、卤代-C2-6链烯氧基、C3-6-环烷氧基(被卤素任意取代)C3-6-环烷基甲氧基、卤代-C3-6-环烷基甲氧基、C1-6-烷硫基(被卤素任意取代)、C1-6-烷基亚磺酰基、C1-6-烷基磺酰基、苯氧基、卤代苯氧基、氨基、C1-4-烷氨基、二-C1-4-烷氨基、氰基、硝基和OX基团,这里X是酰基R7CO或磺酰基R7SO2,其中R7是C1-6-烷基(被卤素、C1-4-烷氧基、C1-4-烷氨基或二-C1-4-烷氨基任意取代)、C3-6-环烷基(被卤素任意取代)、C2-6-炔基(被卤素任意取代)、C2-6-链烯基或苯基;R2、R3和R4可以相同或者不同,它们是被卤素任意取代的C1-4-烷基、C1-4-烷氧基和/或C1-4-烷硫基;R5和R6可以相同或者不同,它们是氢、C1-4-烷基或C3-6-环烷基(其每个基团被卤素任意取代),C1-4-烷氧基、C1-4-烷硫基、C1-4-烷氨基或二-C1-4-烷氨基;被卤素任意取代的C2-6-链烯基或C2-6-炔基,或被-OY取代的C1-6-烷基,这里的Y是氢、酰基R7CO或磺酰基R7SO2,其中R7有上述含义。
在化合物中,与烷基、环烷基、烷氧基、烷硫基、链烯基、炔基、链烯氧基、炔氧基、环烷氧基、环烷基甲氧基、苯基或苯氧基等基团相连的符号“卤”表示一个或多个氢原子被囟素取代。术语卤素是熟知的氟、氯、溴和碘。
化合物特别好的基团是下列这些基团:
其中
R1是在对位由卤素(特别是氯)、甲氧基、乙氧基或二氟甲氧基取代的苯基,和在间位由氟或氯任意取代的苯基;
R2、R3和R4是甲基;
R5是氢;和
R6是氢或者甲基。
本发明包括各种异构体以及这些异构体的混合物。
本发明的化合物能按已知方法制备得到。一个方法包括式Ⅱ化合物用通式Ⅲ的醇处理:
其中R1、R2、R3和R4具有上述含义,并且Z是卤素或羟基。
其中R5和R6具有上述含义。
就通式Ⅱ(其中Z为卤素)的化合物的反应来说,式Ⅲ的醇是用羧酸卤化物(参考L.F.Tietze等“有机化学实验中的反应与合成”1981年第115页)酰化的,该反应能适合于在酸接受体存在下,进行(参看Georg Thieme Verlag“Houben-Weyl有机化学方法”第Ⅷ卷第541页ff(1952年))
常规的碱性物料适于作酸接受体,例如:脂肪族、芳香族和杂环的胺类,如三乙胺、二乙胺、哌啶和吡啶。反应能在有或无溶剂的情况下
进行。除了酸接受体外,合适的溶剂或其混合物包括任意地脂肪族和芳香烃如:石油醚、苯、甲苯、二甲苯、二氯甲烷、氯仿、四氢化碳、1,2-二氯乙烷和氯苯;醚类如:乙醚和丁醚、甲基叔丁基醚、四氢呋喃和二噁烷;酮类如:丙酮、甲基乙基酮和甲基异丙基酮,和腈类如:乙腈和丙腈。
反应物料一般是以化学计算量来使用的,有时能使用一个或多个反应物料过量,但是通常并没有好处。
反应通常在0℃以上用足够的速度进行。因为反应通常是放热的,所以进行冷却一般是有利反应进行。
当通式Ⅱ化合物(其中Z为羟基)与式Ⅲ醇反应时,这是羧酸的酯化作用(参见Georg Thieme Verlag“Houben-Weyl,有机化学方法”第Ⅷ卷第516页ff(1952年)),该酯化作用能以任意地通过加入如硫酸、卤化氢或磺酸或离子交换树脂等催化剂的已知方法加速进行,并且能通过用如共沸蒸馏从反应混合物中除去水或通式Ⅰ酯的方法,使酯化作用的平衡朝期望的方向进行。
本发明通式Ⅰ的化合物还能几乎按照所有制备酯的实用常规方法来合成,例如能从通式Ⅱ羧酸衍生的羧酸酐,或还能用这些羧酸盐与任意取代的通式Ⅳ卤化物起反应来合成,
其中R5和R6具有上述含义,并且Z是卤素。
用作通式Ⅱ原料的苯乙酸类通常是已知的,它们能按已知的方法来制备(如看“有机化学杂志”32(9)1967年第2799和2801页;“柏林化学”116(1938年)第3708-3724页)。
其中R1、R2、R3和R4具有上述含义。
通式Ⅱ苯乙酰基卤化物(其中Z为卤素)能用已知方法从这些游离酸得到。
通式Ⅲ的醇是一般的商业产品或能按通常已知的方法来制备。
一般地说,本发明的化合物是无色的油,其能高度溶于所有实用的有机溶剂,但几乎不溶于水。
本发明的化合物具有杀虫和杀螨的活性,并因此能用于灭除大量的昆虫和蜱螨,包括动物的外寄生虫。例如包括鳞翅目如:菜蛾属xylostella,黄条粘虫littoralisx棉铃虫属armigera,和粉蝶属brassicae;双翅目如:家蝇,实蝇capitata,Erioischiabrassicae,绿蝇sercata和伊蚊属aegypti;同翅目包括蚜虫如:日本修尾蚜vicae和飞虱lugens;鞘翅目如:Phaedon cochleariae,花象甲属格兰菌和玉米根蠕虫(条叶甲属类如:Diabrotica undecimpunctata);直翅目如:小蠊属germanica;蜱类如:牛蜱属microplus和虱类如:牛Damalinia和小牛长虱属,以及蜘蛛螨类如:红叶螨属urticae和全爪螨属ulmi。本发明的化合物以一个意想不到的方法用于灭除昆虫,特别是灭除害虫,及其在技术水平上显示了有价值的改进。
按照本发明的化合物能在0.0005-5%最好为0.001-1%的浓度使用,该浓度是以每100毫升组合物中活性物料的克数来计算的。
本发明的化合物能单独使用或以彼此混合或与别的杀虫剂混合的形式使用。根据所期望的效果能随意地加入其它的植物保护剂或杀虫剂组合物,例如杀虫剂、杀螨剂或杀真菌剂。
在作用的强度和速度方面的改进是能达到的例如通过加入适当的辅
助剂,如有机溶剂、湿润剂和油,这种添加剂的加入可减少剂量。
适宜的混合物加入物还可包括例如下面一组的磷脂类:磷脂酰胆碱、磷脂酰胆碱水合物、磷脂酰乙醇胺、N-乙酰基-磷脂酰乙醇胺、磷脂酰肌醇、磷脂酰丝氨酸、脱酯酸磷酸酯或磷脂酰甘油。
指定的活性成份或它们的混合物能同例如液体和/或固体载体和/或稀释剂添加剂一起使用,并能随意地伴有粘结、湿润、乳化和/或分散辅助剂,被用作为粉末、粉剂、颗粒、溶液、乳剂或悬浮液来使用。
适宜的液体载体是如脂肪族和芳香族烃类如苯、甲苯、二甲苯、环己酮、异佛尔酮、二甲亚砜、二甲基甲酰胺、其它矿物油馏份和植物油。
适宜的固体载体包括矿物土如:tonsil、硅胶、滑石、高岭土、attapulgite、石灰石、硅酸和植物产品如谷粉。
这里使用作为表面活性剂例如:木素磺酸钙、聚氧乙烯烷基苯基醚、萘磺酰及其盐、苯酚磺酸及其盐、缩合甲醛、脂肪醇硫酸酯,以及取代的苯磺酸及其盐。
