A Novel Stereoselective Route to cis-Olefins via Addition of Vinyl Cuprates to αβ-Unsaturated Sulphones and Subsequent Desulphonylation

Dialkenylcuprates, generated by addition of dialkylcuprates to acetylene, react with αβ-unsaturated sulphones to give cis-γδ-unsaturated sulphones which can be easily desulphonylated with retention of the double-bond configuration.
