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.
证明了可见光诱导的炔烃的Co-或Cu催化的硒代磺酰化反应,用于合成β-(硒代)乙烯基砜。该方法利用低成本的钴盐或金属铜作为催化剂。该反应通过在温和条件下将炔磺酸的光诱导自由基加成到炔烃上,以实现炔烃的1,2-硒磺酰化。
