Mizoroki–Heck reaction of unstrained arylketone with acrylate/styrene is accomplished via palladium-catalyzed ligand-promoted C–C bond cleavage. Various (hetero)arylketones are compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived arylketones demonstrate the synthetic utility

hydroaminoalkylation of activated alkenes that provides the β-selective products. The chain-walking of a Ni–H intermediate toward a carbonyl allows for the hydroaminoalkylation of unactivated alkenes at remote sp3 C–H sites. This method tolerates a broad substrate scope of both amines and alkenes as well as providing a streamlined synthesis of value-added β-amino acid derivatives from readily available
