An intermolecular cycloaddition reaction has been developed, where o-arylcarboxybenzonitriles react with alkynes to afford coumarins in the presence of Ni(0)/P(CH2Ph)3/MAD as a catalyst. The reaction process displays an unusual mechanistic feature - the cleavage of two independent C - CN and C - CO bonds.
