2-Arylpropyl ether or thioether derivatives represented by the following general formula [I]: ##STR1## wherein Ar stands for an aryl group, R stands for a methyl or ethyl group, Y stands for an oxygen or sulfur atom, and B stands for a group represented by the following formula [II]: ##STR2## or the following general formula [III]: ##STR3## wherein Z stands for an oxygen or sulfur atom or a carbonyl or methylene group, R.sup.1 stands for a hydrogen or halogen atom or a lower alkyl group or a lower alkoxy group, and n is an integer of from 1 to 5 with the proviso that when n is 2 or more, the groups R.sup.1 may be the same or different, are produced by reacting a compound represented by the following formula (V): ##STR4## with a compound represented by the following formula (VI): B--CH.sub.2 --D (VI) wherein Ar, R and B are defined above, A is a halogen atom and D is Y--H in which Y is as defined above, in the presence of a base in dimethylsulfoxide or sulfolane. The compounds thus prepared have excellent insecticidal and acaricidal activities while the toxicity of these compounds are very low.
以下是2-芳基丙基醚或硫醚衍生物的通式[I]:##STR1##其中Ar代表芳基,R代表甲基或乙基,Y代表氧原子或硫原子,B代表以下通式[II]所代表的基团:##STR2##或以下通式[III]的通式:##STR3##其中Z代表氧原子或硫原子或羰基或亚甲基基团,R.sup.1代表氢原子或卤素原子或较低的烷基基团或较低的烷氧基基团,n是1到5之间的整数,但当n为2或更多时,基团R.sup.1可以相同或不同。这些衍生物是通过将以下通式(V)所代表的化合物与以下通式(VI)所代表的化合物反应而制备的:##STR4##其中Ar,R和B如上所定义,A是卤素原子,D是Y-H,其中Y如上所定义,在二甲基亚砜或硫代乙醇中,在碱的存在下。这样制备的化合物具有优异的杀虫和杀螨活性,而这些化合物的毒性非常低。
