Abstract

Bis-(amino)cyclopropenylidene has been utilised as a non-covalent Brønsted base catalyst in the 1,6-conjugate addition of carbon nucleophiles to p-QMs. This protocol makes it possible to access unsymmetrical diaryl- and triarylmethanes in good to excellent yields. Further, this catalyst was also explored in the 1,4-conjugate addition of carbon nucleophiles to enone systems.
