demonstrated upon their reactions with alkynes. Both the electrophilicity of the carbene car— hon atom and the facile substitution of carbon monoxide are used for selective carbon carbon bond formation. Nucleophilic alkynes (ynamines) add to the carbene carbon atom and then undergo insertion into the metal carbene bond. Chromium(O) is effective as a template in the annulation of carbene ligands bearing aromatic
