NUCLEOPHILIC ADDITION TO STYRYL SULPHONES. PART I. A STUDY ON THE REGIOCHEMISTRY.

Benedetti, F.,Fabrissin, S.,Risaliti, A.

, p. 3887 - 3894 (2007/10/02)

Styryl sulphones undergo nucleophilic addition, with the nucleophile adding at the α- or the β-position, with respect to the sulphone group; β-attack is normally favoured over α-attack.Factors which can change the regioselectivity in favour of the addition of the nucleophile to the α-position are discussed for heteronucleophiles as well as carbon nucleophiles.
