Abstract
Abstract Novel compounds of the formula ##STR1## are disclosed in which R 1 is a phenyl, phenoxy, phenylthio, benzyl or heterocyclic radical which may be substituted, and R 2 is hydrogen, a substituted-vinylcyclopropanecarbonyl group, a tetramethylcyclopropanecarbonyl group, or a 1-(substituted-phenyl)-2-methylpropylcarbonyl group. The compounds wherein R 2 is other than hydrogen are insecticides.
