    摘要: The (+), (-) and (.+-.) forms of the compounds of the general formula (I) ##STR1## characterized in that R.sup.1 is a halo group; or a lower alkyl, lower alkoxy or lower alkylthio group, each of which may be substituted with one or more halo groups;R.sup.2 is hydrogen or a methyl group; or R.sup.1 and R.sup.2 together form a methylenedioxy, or a difluoromethylenedioxy group or, with the carbon atoms to which they are attached, an aromatic or heteroaromatic ring; andA is one of the groups X or Y ##STR2## wherein X.sup.1 and X.sup.2 are the same or different and each is hydrogen or a fluoro, chloro, bromo or methyl group, with the proviso that if X.sup.1 is a fluoro group, then X.sup.2 should not be a bromo group; and X.sup.3 and X.sup.4 are the same or different and each is hydrogen or a fluoro group; andY.sup.1, Y.sup.2, Y.sup.3, Y.sup.4, Y.sup.5 and Y.sup.6 are the same or different groups and each is hydrogen or a fluoro, bromo, chloro, or methyl group.The compounds (I) are insecticidally active.
