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

An intermolecular Rauhut-Currier reaction between α,β-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.
