Copper(II)-Catalyzed Chemo- and Stereocontrolled Synthesis of (E)-Vinyl Sulfones and (Z)-β-Chlorovinyl Sulfones from Terminal Alkynes and Arylsulfonyl Hydrazides

A facile copper(II)-catalyzed regio- and stereocontrolled synthesis of vinyl sulfones from terminal alkynes and arylsulfonyl hydrazides is described. Depending on the source of copper(II), two different kinds of vinyl sulfones, (E)-vinyl sulfones and (Z)-β-chlorovinyl sulfones were obtained and the addition of cyclohexanone played an important role in the reaction. These reactions display excellent chemoselectivity as well as stereoselectivity.

Electron Donor-Acceptor Complex Enabled Decarboxylative Sulfonylation of Cinnamic Acids under Visible-Light Irradiation

Visible-light-induced decarboxylative sulfonylation of cinnamic acids with aryl sulfonate phenol esters enabled by the electron donor-acceptor complex is developed. The method offers a mild and green approach for the synthesis of vinyl sulfones with excellent functional group compatibility under photocatalyst and oxidant-free conditions.

Copper-catalyzed radical reaction of N -tosylhydrazones: Stereoselective synthesis of (E)-vinyl sulfones

A new chemistry of hydrazines that is a copper-catalyzed radical reaction to synthesize vinyl sulfones from readily available N-tosylhydrazones has been described. The protocol provides a novel strategy for the synthesis of various vinyl sulfones 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 one-pot synthesis of alkynes from N-tosylhydrazones has been achieved. The studies provide important complementary approaches for the syntheses of vinyl sulfones and alkynes.
