ABSTRACT:
O,S-Dialkyl ((nitrogen heterocyclyl)carbonyl)-phosphoramidothioates are prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates with selected 5 and 6 membered nitrogen heterocycles, such as thiomorpholine and tetrahydroquinoline, and found to be effective plant systemic and contact insecticides. O,S-dimethyl ((4-thiomorpholinyl)carbonyl)phosphoramidothioate, for example, is prepared from O,S-dimethyl phosphoroisocyanatidothioate and thiomorpholine and found to control aster leafhopper when applied to rice plants.
