Abstract

An efficient 1,4-addition of Me₃SiCN to aromatic enones has been achieved with excellent yields (91%-99%) using CsF (1 mol%) as the catalyst and H₂O (4 equiv.) as the additive in refluxing dioxane within 7 h. The perfect regioselectivity is proposed accounting from H₂O-facilitated reversion of the 1,2-adduct in the presence of CsF and subsequent irreversible 1,4-addition reaction.
