Solvent-free synthesis and structure of 2-naphthol derivatives of resorcinarenes

Abstract 2-naphthol derivatives of resorcinarenes were synthesized by solvent-free 1,4 Michael addition reactions in yields up to 76%. This result is significantly better than in case of reactions in solution. Based on experimental results and previously known similar reactions a mechanism is proposed involving an in situ generated o -quino methide derivative of resorcinarene.
