Organometallic bonding
WitrynaOrganometallic compounds are compounds having a metal-carbon linkage in which the carbon belongs to an organic molecule. The metal-carbon bond is covalent in nature. Metalloid elements such as tin, silicon, and boron are also known to form organometallic compounds that are used in a wide variety of industrial chemical reactions . WitrynaNew mechanistic studies have uncovered the role of salts and additives in the formation of active species in nickel-catalysed reactions. These results address ‘a fundamental gap in knowledge’, according to Eva Hevia, an expert in organometallic chemistry at the University of Bern, Switzerland, who wasn’t involved in the study.‘Such fundamental …

The need for additional nomenclature for organometallic compounds became apparent in the mid-1950s when Dunitz, Orgel, and Rich described the structure of the "sandwich complex" ferrocene by X-ray crystallography where an iron atom is "sandwiched" between two parallel cyclopentadienyl rings. Cotton later proposed the term hapticity derived from the adjectival prefix hapto (from the Greek haptein, to fasten, denoting contact or combination) placed before the name of the olefin… Witryna18.9: Organometallic Reagents.
