Transition metal vinylidene complexes are organometallic species isomeric to pi- and sigma-alkynyne complexes. Due to their mechanistic novelty and potential for new reaction discovery, these metal-coordinated unsaturated carbenes have emerged as highly useful intermediates for alkyne functionalization. For the past years, we have investigated C–C bond-forming reactions that make use of alkynes as substrates through the intermediacy of metal vinylidene complexes. Presented here are the results of our investigations directed at the development of novel cyclization reactions for the formation of carbo- and hetero-cyclic compounds. The scope, mechanism, and utility of these processes will be discussed.
