Gold/photoredox-cocatalyzed atom transfer thiosulfonylation of alkynes: Stereoselective synthesis of vinylsulfones
摘要:
We report a gold and photoredox combined radical approach for the rapid synthesis of thio-functionalized vinylsulfones from alkynes. Key features of this method include very mild conditions, broad substrate scope, excellent regio- and stereoselectivties, and 100% atom economy. (C) 2019 Elsevier Ltd. All rights reserved.

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 freeradical addition of selenosulfonates to alkynes for the 1,2-selenosulfonylation of alkynes undermildconditions.
