An atom-economical strategy for the C–H alkenylation and C–H allylation of arenes by employing cyclopropenes as versatile alkenylating and allylating reagents is reported, catalyzed by cobalt. The Co-catalyzed C–H alkenylation process involves sequential C–H and C–C bond cleavage. Under the optimized conditions, broad-ranging alkenylated (hetero)arenes were synthesized with complete (E)-stereoselectivity

A transition-metal-free three-component reaction of cyclopropene, aldehyde and amine is reported. The reaction is a new demonstration of formal [3+2] cycloaddition triggered by ring-opening of cyclopropenes bearing electron-withdrawing substitutes. The...
hydroacylation of cyclopropene is disclosed for synthesizing various 2-acylcyclopropane derivatives under mild reaction conditions. High functional group tolerance of this protocol features a novel route to access a divergent synthesis of acylated cyclopropane in a diastereoselective manner by photoinduced decarboxylation of α-ketoacid followed by acyl radical addition to cyclopropene. Additionally, the
