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.

Abstract
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.File in questo prodotto:
