Bis(amino)cyclopropenylidene Catalyzed Rauhut-Currier Reaction between α,β-Unsaturated Carbonyl Compounds and para-Quinone Methides

An intermolecular Rauhut-Currier reaction between alpha,beta-unsaturated carbonyl compounds and p-quinone methides has been developed by employing bis(amino)-cyclopropenylidene as a catalyst. This protocol allows access to a variety of vinyl diarylmethane derivatives in moderate to good yields.
