A novel one-pot approach for the synthesis of (Z)-vinylic selenosulfides is demonstrated through the thioselenation of a wide range of alkynes with unsymmetrical diorganoyl dichalcogenides (RSSePh) catalyzed by cesium hydroxide monohydrate, avoiding the use of the transition metal catalyst and the previous preparation of chalcogen alkynes. Other outstanding features include mild reaction conditions, high regio- and stereo-selectivity, excellent yields and wide functional group tolerance.

A highly chemo-, regio-, and stereoselective method for the synthesis of (Z)-vinylic selenosulfides and (Z)-vinylic tellurosulfides in a one-pot reaction of terminal alkynes, diaryl disulfides, and diaryl diselenides (ditellurides) catalyzed by simple bas
