Abstract
Compounds of the formula ##EQU1## wherein R.sup.1 and R.sup.2 individually are alkyl or alkenyl; R.sup.4 is hydrogen, alkyl or haloalkyl; R.sup.3 and R.sup.5 are hydrogen or alkyl and R.sup.6 is alkyl, haloalkyl, aryl, alkoxy, aryloxy, alkylthio, or amino are produced by the acid-catalyzed condensation of a 1,3-dicarbonyl compound of the formula ##EQU2## with a phosphoroamidothioate compound of the formula ##EQU3## wherein R.sup.1 and R.sup.6 are as defined above. The compounds are highly active insecticides, with low mammalian toxicity.
