A visible light-induced Co- or Cu-catalyzed selenosulfonylation of alkynes for the synthesis of β-(seleno)vinyl sulfones is demonstrated. This method utilizes a low-cost cobalt salt or metal copper as the catalysts. The reaction goes through a photoinduced free radical addition of selenosulfonates to alkynes for the 1,2-selenosulfonylation of alkynes under mild conditions.

The oxidation of sulfohydrazides with benzeneselenic acid provides an efficient and convenient preparation of selenosulfonates.Se-Phenyl p-tolueneselenosulfonates was also produced in good to excellent yield from the reaction of p-toluenesulfohydrazide with PhSeCl, PhSeBr, or PhSeCl3.Sulfohydrazide react with sulfenyl halides or with PhSBr3 to produce thiosulfonates generally high yield.The treatment of p-toluenesulfohydrazide with benzenetellurinic acid, PhTeCl3, or PhTeBr3, afforded only diphenyl ditelluride and not the corresponding tellerosulfonate.

A number of thioacetals were deprotected with benzeneseleninic anhydride in good yield.The reaction worked particularly well for hindered spiro-1,3-dithiolans of 2,2,6-trimethylcyclohexanone and fenchone, and in examples where other literature methods had failed.
