Aromatic enamines and diarylacetylenes may be obtained in a novel one-step synthesis involving the condensation of N-arylmethyl heterocycles with aromatic imines in the presence of a strong base. The enamines are isolable intermediates on the route to diarylacetylenes via the elimination of the nitrogen heterocycle.

Radical addition to vinyltriazole was developed as a new approach to achieve 1,2,3-triazole ring opening under mild conditions. Through reagent control, excellent chemoselectivity was achieved, giving either nitrile under basic conditions or quinoxaline under neutral conditions. Reactivities made this method an attractive new reaction mode.
