Bioorganometallic Chemistry has become a mature area of science and is comprehensively covered by leading experts in this book. Naturally occuring bioorganometallic complexes, such as vitamin B₁₂ and recently discovered iron and nickel hydrogenases, including a possible role of the latter in the geochemical theory of the origin of life, are considered. The possible formation of carbene complexes of cytochrome P450 enzymes in various metabolisms of xenobiotics is also discussed. The bioorganometallic chemistry is considered to provide not only organometallic receptors such as...
