radical reaction to synthesize vinylsulfones from readily available N-tosylhydrazones has been described. The protocol provides a novel strategy for the synthesis of various vinylsulfones including α, β-disubstituted ones and terminal ones. The advantages of the transformation include excellent E stereoselectivity, broad substrate scope, low cost of reagents, and convenient operation. A novel and efficient
