Organometallic Chemistry is the study of chemical compounds containing at least one chemical bond between a carbon atom of an organic compound and a metal, including alkaline, alkaline earth, transition metal, and sometimes broadened to include metalloids like boron, silicon, and tin, as well. Organometallic compounds are widely used both stoichiometrically in research and industrial chemical reactions, as well as in the role of catalysts to increase the rates of such reactions where target molecules include polymers, pharmaceuticals, and many other types of practical products.
