Abstract
A method of making an organic metal salt or complex is disclosed by reacting a heavy metal hydroxide with an organic Lewis acid or salt thereof in the presence of a gaseous catalyst such as a form of CO.sub.2. The reaction may be controlled by the addition of a buffering agent. Other gaseous catalysts such as CO and SO.sub.2 or their related salts, can be employed. The method produces organic metal complexes or salts in a pure second salt-free state either in a solution or solid state.
