Alkylcopper compounds RCu react with salt-free cuprous acetylides R′CCCu to give disubstituted acetylenes, R′CCR, the products of unsymmetrical coupling. Conjugated acetylenic acids react with methylcopper in the absence of salts to give similar products resulting from decarboxylation followed by coupling.
