(Cyclopropylidenecyclohexyl)benzene derivatives, a kind of methylenecyclopropane (MCP) containing a cyclohexyl group, can undergo an interesting tandem intramolecular C−H and C−C bond activation through dehydrogenated rearrangement in the presence of AuPPh3Cl/AgOTf by transferring three hydrogen atoms from cyclohexane to cyclopropane, affording the corresponding biaryl derivatives in moderate to good

Isopropenylbiaryl derivatives were produced in moderate to good yields at high temperature from the reaction of methylenecyclopropanes (MCPs) 1 in the presence of palladiumacetate 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
