Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well.
General chemical structure of a metallocene compound, where M is a metal cation. A metallocene is a compound typically consisting of two cyclopentadienyl anions (C 5 H − 5, abbreviated Cp) bound to a metal center (M) in the oxidation state II, with the resulting general formula (C 5 H 5) 2 M. Closely related to the metallocenes are the metallocene derivatives, e.g. titanocene dichloride or ...
Main group organometallic chemistry concerns the preparation and properties of main-group elements directly bonded to carbon. The inventory is large. The inventory is large. The compounds exhibit a wide range of properties, including ones that are water-stable and others that are pyrophoric . [ 1 ]
Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2.The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.
The most famous example is Vaska's complex (IrCl(CO)(PPh 3) 2), [PtCl 4] 2−, and Zeise's salt [PtCl 3 (η 2-C 2 H 4)] −. In such complexes, the d z 2 orbital is doubly occupied and nonbonding. Many catalytic cycles operate via complexes that alternate between 18-electron and square-planar 16-electron configurations.
AgCl + (CH 3) 3 C 6 H 2 MgBr → 1/4 [(CH 3) 3 C 6 H 2 Ag] 4 + MgClBr. A variety of organosilver compounds include phosphorus ylides. A simple example is the pentafluorophenylsilver complex of methylenetriphenylphosphorane: [8] AgC 6 F 5 + Ph 3 P=CH 2 → Ph 3 P=CH 2 −AgC 6 F 5. Alkenylsilver compounds are also more stable than their ...
Diethylmercury results from the reaction of mercury chloride with two equivalents of ethylmagnesium bromide, a conversion that would typically be conducted in diethyl ether solution. [13] The resulting (CH 3 CH 2) 2 Hg is a dense liquid (2.466 g/cm 3) that boils at 57 °C at 16 torr. This extremely toxic compound is slightly soluble in ethanol ...
Organozirconium chemistry is the science of exploring the properties, structure, and reactivity of organozirconium compounds, which are organometallic compounds containing chemical bonds between carbon and zirconium. [2] Organozirconium compounds have been widely studied, in part because they are useful catalysts in Ziegler-Natta polymerization.
