摘　　要：Comprehensive Summary A visible-light mediated exclusively regioselective synthesis of 2,2-disubstituted thio-functionalized tetrahydrofurans,tetrahydro-pyrans and oxepanes has been described through an operationally simple and mild photoredox protocol.Thiyl radical generated from N-phenylsulfenyl phthalimide by photoredox catalysis was proven to be the key reactive intermediate in this reaction.
