The (+), (-) and (.+-.) forms of the compounds of formula I ##STR1## wherein R.sup.1 is hydrogen or a methoxy, ethoxy, propoxy, methylthio, ethylthio, propylthio, fluoro, chloro, bromo, methyl, ethyl, nitro or amino group, and R.sup.2 is a hydrogen or methyl group or R.sup.1 and R.sup.2 together form a methylenedioxy group; R.sup.3 is hydrogen, or a lower alkyl group, or one of the following groups (a) to (d): (a) m-phenoxybenzyl (b) 2-benzyl-4-furylmethyl (c) .alpha.-cyano-m-phenoxybenzyl (d) 3,4-methylenedioxy-benzyl, and R.sup.4 and R.sup.5 are the same or different groups and each is a fluoro, bromo, chloro or methyl group. The compounds of formula I in which R.sup.3 is one of group (a) to (d) are extremely active as insecticides (except when R.sup.1 is an amino group). The compounds also possess the property of contact repellency to insects.
公式I的化合物有三种形式:(+), (-)和(.+-.),其中R.sup.1是氢或甲氧基、乙氧基、丙氧基、甲硫基、乙硫基、丙硫基、氟、氯、溴、甲基、乙基、硝基或氨基基团,而R.sup.2是氢或甲基基团或R.sup.1和R.sup.2一起形成一个亚甲基二氧基基团;R.sup.3是氢或较低的烷基基团,或以下四种基团之一(a)对苯氧基苯甲基(b)2-苄基-4-呋喃甲基(c).alpha.-氰基对苯氧基苯甲基(d)3,4-亚甲二氧基苯甲基,而R.sup.4和R.sup.5是相同或不同的基团,每个基团都是氟、溴、氯或甲基基团。当R.sup.3是(a)到(d)基团之一时,公式I的化合物作为杀虫剂非常活跃(除了当R.sup.1是氨基基团时)。这些化合物还具有对昆虫的接触驱避性能。
