... Organocopper intermediates are also involved in several procedures for coupling of two organic reactants to form a new carbon-carbon bond. Classical example of this type of reaction is the Ullman coupling, which is done by heating an aryl halide with a copper-bronze alloy. Good yields by this me ...
