A general and practical method of synthesis of α,β-unsaturated sulphonates (25 examples) by the Wittig-Hornerreaction is described. Reactions with the salts 2 and carbonyl compounds are not very stereoselective. On the contrary, reactions with esters 1 gave high yields of (E)-α,β-unsaturated sulphonic esters.
