摘要
We have developed a highly efficient synthetic route to beta-ketosuifones via AgNO3 catalyzed oxysulfonylation of alkenes using thiophenols in the presence of air (O-2) and K2S2O8 as eco-friendly oxidants. Thiophenols have been used as sulfonylation precursors for the first time in a dioxygen activation based radical process. Moreover, the protocol also offers a new and convenient method for the synthesis of beta-hydroxysulfides at room temperature without the use of any initiator.
