Die organischen Verbindungen und Komplexe von Germanium,Zinn und Blei

This field is of special interest within the organometallic chemistry, which was and still is one of the most developing areas of chemistry for twenty years. The electronic structure around the atoms of germanium, tin, and lead favors both polar and radical reactions, and a plentiful coordination chemistry, too. Modern quantum chemistry arrived at these heavy atoms and allows better understanding also of low valent species, R₂M. Chiral compounds with asymmetric Sn atoms, an object aimed at since 1905, have been prepared now, and dynamic stereochemistry has been studied. Industrial use of organotins has grown quickly and includes stabilization of plastics and plant and material protection as well. Biomethylation and environmental problems open this field both to biochemists and ecologists.
