Carboxylic acid esters of the formula (I), ##STR1## wherein X is a hydrogen atom, or a C.sub.1 -C.sub.3 alkyl or a C.sub.1 -C.sub.3 alkoxyl group or a halogen atom linked to the meta or para position and R.sub.1 is a group of the formula (II) or (III), ##STR2## wherein R.sub.2 is a hydrogen atom or a methyl group, and when R.sub.2 is a methyl group R.sub.3 is also a methyl group, and when R.sub.2 is a hydrogen atom R.sub.3 is a group of the formula, ##STR3## (wherein R.sub.5 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, vinyl or a C.sub.1 -C.sub.3 alkoxymethyl group, R.sub.6 is a hydrogen or halogen atom or a methyl group, or, taken together, R.sub.5 and R.sub.6 may form a tetramethylene group by connecting together at ends thereof), R.sub.4 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxyl or 3,4-methylenedioxy group, n is 1 or 2 and Y is a isopropyl or cyclopropyl group. These carboxylic acid esters are useful as insecticides and acaricides.
公式(I)的羧酸酯,其中X是氢原子,或C.sub.1-C.sub.3烷基或C.sub.1-C.sub.3烷氧基或连接到间位或对位的卤素原子,而R.sub.1是公式(II)或(III)的基团,其中R.sub.2是氢原子或甲基基团,当R.sub.2是甲基基团时,R.sub.3也是甲基基团,当R.sub.2是氢原子时,R.sub.3是公式的基团,其中R.sub.5是卤素原子或C.sub.1-C.sub.3烷基,乙烯基或C.sub.1-C.sub.3烷氧甲基基团,R.sub.6是氢原子或卤素原子或甲基基团,或者R.sub.5和R.sub.6可以通过在其末端连接在一起形成四亚甲基基团,R.sub.4是卤素原子或C.sub.1-C.sub.3烷基、C.sub.1-C.sub.3烷氧基或3,4-亚甲二氧基基团,n为1或2,Y为异丙基或环丙基。这些羧酸酯可用作杀虫剂和杀螨剂。
