✦ Synopsis

Dicobalt carbonyl complex mediates an intermolecular carbonylative coupling reaction between alkynylsilanes. The reaction proceeds under atmospheric pressure of argon and directly provides free cyclopentadienones in high yields (up to 99%).

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
