Abstract
O,S-Dailkyl ((nitrogen heterocyclyl)carbonyl)phosphoramidothioates are prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates with selected five and six membered nitrogen heterocycles and found to be effective plant systemic and contact insecticides. Ethyl 1-(((methoxy(methylthio)phosphinyl)amino)carbonyl)-4-piperidinecarboxylate , for example, is prepared from O,S-dimethyl phosphoroisocyanatidothioate and ethyl 4-piperidinecarboxylate and found to control aster leafhopper when applied to rice plants.
