Under nickel(O) mediation, trimethylsilyl(iso)cyanide serves as both a useful synhydrocyanating agent and a carbonylating agent for alkynes. Metallacyclopentadienes have often been proposed as essential intermediates in the cyclotrimerization of alkynes into benzene derivatives.' Specifically in the
