title: Palladium-Catalyzed Regiodivergent Substitution of Propargylic Carbonates.
abstract: The palladium(0)-catalyzed, ligand-controlled, regioselective addition of diaryl acetonitrile pronucleophiles to propargylic carbonates is reported. Selective formation of either terminal 1,3-dienyl or propargylated products is proposed to arise from a change in reaction mechanism controlled by the denticity of the coordinating ligand.
