Main Group Organometallic Chemistry
Main group organometallic chemistry concerns the preparation and properties of main-group elements directly bonded to carbon. The inventory is large. The compounds exhibit a wide range of properties, including ones that are water-stable and others that are Pyrophoricity, pyrophoric. Many are very useful themselves, as chemical reagents, or as catalysts. Classification and structure Main group organometallic chemistry are typically categorized according to their position in the periodic table. Another possible classification scheme organizes these compounds according to the nature of the organic substituent: alkyls, aryls, vinyls, etc. Most homoleptic organo-main group compounds adopt a characteristic oxidation state: RLi, R2Be, R3B/R3Al, R4Si, R3P, R2S. Members where the simplest stoichiometry violates the octet rule often aggregate by formation of bridging alkyl groups. When the alkyl group bridges two main group elements, the bonding is called three-center two-electron bonds ...
