A simple and efficient visible-light mediated synthesis of thiosulfonates via a radical-radical coupling of sulfenyl radicals and arylsulfonyl radicals was developed. The reaction of thiols, aryldiazonium tetrafluoroborates and DABSO proceeded at room temperature using 5 mol% eosin Y. The reaction displayed wide functional group tolerance and delivered the unsymmetrical thiosulfonates in good to excellent yields.

A unique phenylboronic acid-catalyzed dimerization-sulfonylation ofS-benzyl thiosulfonates has been disclosed. A metal-free tandem construction of S-S and C-S bonds is an operationally simple method to access a wide range of benzyl disulfanylsulfone derivatives in high to excellent yields. Moreover, the robustness of this tandem transformation has been demonstrated by gram-scale reactions, and a plausible mechanism is also proposed.

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.
