Abstract

Isopropenylbiaryl derivatives were produced in moderate to good yields at high temperature from the reaction of methylenecyclopropanes (MCPs) 1 in the presence of palladium acetate under ambient atmosphere by tandem intramolecular C–H and C–C bond activation and aromatization through dehydrogenated rearrangement of MCPs 1. A plausible mechanism has been proposed on the basis of deuterium labeling and control experiments.
