Copper and Silver Acetylides in Organic Synthesis

A review of the reactions of copper, silver, and gold acetylides with halides, aryl halides, unsaturated halogen compounds, diazonium salts, halides of organic acids, and organometallic compounds. Information on the structure of copper and silver acetylides and their physical properties is given. The mechanisms of the reactions of copper acetylides with the above types of compounds and the mechanism of the oxidative condensation of acetylenes are considered. The properties of copper and silver acetylides are compared with the properties of the cyanides of these metals. Bibliography of 127 references.
