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 groups (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.
化合物I的(+), (-)和(.+-.)形式的公式,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,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,或低碳基基团,或以下组之一(a)至(d): (a) m-苯氧基苄基,(b) 2-苄基-4-呋喃基甲基(c).alpha.-氰基-m-苯氧基苄基(d) 3-4-亚甲基二氧基苄基,R.sup.4和R.sup.5是相同或不同的基团,每个基团是氟,溴,氯或甲基基团。当R.sup.3是(a)至(d)中的一组时,公式I的化合物作为杀虫剂非常活泼(除非R.sup.1是氨基基团)。这些化合物也具有对昆虫的接触驱避性能。
