AbstractAerobic dehydrogenative sulfenylation of H‐phosphonites, and phosphine oxides with aryl/alkylsulfonyl hydrazides catalyzed by a sub‐stoichiometric amount of copper iodide has been accomplished. This protocol is compatible with functional groups, and results in various thiophosphate derivatives in good to high yields.magnified image

An ambident electrophilicity of phosphinicacid thioesters is disclosed. Unexpected carbon-sulfur bond formation took place in the reaction between phosphinicacid thioesters and benzyl Grignard reagents. The developed method for benzyl sulfides has a wide substrate scope and was applicable for the synthesis of a drug analog.
