Non-hetematom stabilized carbene complexes can be generated in solution by mild thermolysis (500 C) of 4hexynyl and Sheptynyl (methoxymethylene) complexes of chromium and tungsten pentacarbonyl. These intermediates react with acetylenes to give a new type of two-alkyne annulation product. In the abs
