Herein, we have developed metal and oxidant-free visible light-promoted alkene vs. alkyne regio-And chemoselective radical cascade cyclization of electronically unbiased 1,6-enynes with chalcogens to synthesize substituted pyrrolidines bearing chalcogens. The reaction generated three new bonds, namely, C-SO2, C-C, and C-Se under extremely mild conditions. Furthermore, we achieved regio-And chemoselective mono-addition of aromatic thiophenols with unactivated 1,6-enynes. The key features of this protocol are broad substrate scope, environment-friendly conditions, operational simplicity, atom economy, and amenability to gram-scale synthesis. The mechanistic studies corroborate that the reaction proceeds via a radical pathway.

The electrochemical oxidative cross-dehydrogenative coupling of arylsulfinic acids with thiophenols was achieved via a radical process. A wide range of arylsulfinic acids and substituted thiophenols were found to be tolerated, providing unsymmetrical thio

A copper-catalyzed sulfonylation of disulfides was achieved using sodium sulfinates in air. The reaction formed various sulfur-sulfone bonds efficiently and afforded thiosulfonates in good yields. Selenosulfonates could also be prepared with this procedure. Furthermore, both chalcogenide groups on the dichalcogenides were available in these reactions.

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.
