N-Heterocyclic carbene-catalyzed 1,6-addition of aromatic aldehydes to para-quinone methides has been developed. This method could efficiently furnish α,α′-diarylated ketones with good to high yields, which contain various functional groups.

Ethanolysis of 1-aryl-5,7-di-t-butyl-2-phenylspiroocta-1,4,7-trien-6-one 2 proceeds via a vinyl cation generated by opening of the cyclopropene ring, judging from regiospecific ring opening and kinetics (ρ+= -3.0, m = 0.53, and rate dependence on pH of the solvent).
