The cationic ruthenium catalyst Ru3(CO)12/NH 4PF6 was found to be highly effective for the intermolecular coupling reaction of pyrroles and terminal alkynes to give gem-selective α-vinylpyrroles. The carbon isotope effect on the α-pyrrole carbon and the Hammett correlation from a series of para-substituted N-arylpyrroles (- = -0.90) indicate a rate-limiting C-C bond formation step of the coupling reaction.
