Transition-Metal-Free Synthesis of (E)-Vinyl Sulfones from Vinyl Halides in Water

A practical transition‐metal‐free procedure for the synthesis of (E)‐vinyl sulfones through the coupling of vinyl halides with sodium sulfinates in water is reported. The reaction is strongly influenced by the presence of acids, and the use of nBu4NBr promotes its efficiency. A metal‐free procedure...
