A Brønsted acid Ph2P(O)OH can efficiently catalyze the reaction of a Pd(0) complex with an alkyne to produce a novel alkenyl(alkynyl)palladium complex via selective hydropalladation and ligand exchange processes. On the basis of this finding, an efficient Pd(0)/Ph2P(O)OH mediated head-to-tail dimerization of alkynes was disclosed.
