Summary -Allylic sulfones undergo a coupling reaction with organometallic compounds (Mg or Li) not only with copper catalysts but also with iron or nickel salts. With 7,7-disubstituted allylic sulfones and also saturated aliphatic sulfones, however, another reaction was observed whereby two molecules of the starting sulfone are coupled to give symmetrical alkenes. The scope of this reaction was investigated. Elsevier.

α-Lithiated phenylalkyl sulfones, on treatment with various cupric salts, give comparable amounts of the α,α'-dimer and the corresponding vinylic sulfone.With cupric acetate or propionate, dehydrogenation occurs selectively: primary sulfones are converted into α,β-unsaturated sulfones in high yield.

Cupric salts, particularly triflates, convert α-sulphonyl carbanions into α-disulphones.Allylphenylsulphones couple preferentially in the 3-3 'mode.
