Organometallic Chemistry

What is Organometallic Chemistry?

Organometallic Chemistry involves the study of chemical compounds consisting of at least 1 bond between a metal and a carbon atom of an organic compound namely alkaline earth and other transition metals.

n-Butyllithium, an organometallic compound

Organometallic Chemistry merges concepts of both traditional organic and inorganic chemistry. Organometallic compounds find its application in industry and research chemical reactions. It also acts a catalyst in increasing the rate of these reactions. For example homogeneous catalysis.

Organometallic Compounds

Examples of  Organometallic Compounds includes Gilman Reactants consisting of copper and lithium, do, diethylzinc, diethyl magnesium, color,

N-butyllithium, zinc. Ferrocene and Tetracarbonyl nickel are also organometallic compounds consisting of transition metals.

The metal-carbon bond is usually highly covalent in organometallic compounds. Cyanide can be considered as an example for a highly electropositive elements.

Some of these compounds are found in nature such as organomercury compounds, organolead, tetraethyllead, and ferrocene.

Electron Counting

Electron Counting is used in formulating Organometallic Chemistry. The stability of metal carbonyls and other associated compounds are predicted using 18 – electron rule. Isolobal Principle is used to describe reactivity and chemical bonding of an organometallic compound. A standard approach to determining structure is NMR, infrared spectroscopy, and X-ray diffraction. Characteristics of organometallic compounds are requested with fluctuating temperature NMR  and chemical kinetics. Numerous reaction is stated below.
Numerous reactions are stated below:

  • Organometallic Substitution reaction
  • Cyclometalation
  • Hydrometallation
  • Migratory Insertion
  • Nucleophilic Abstraction
  • Carbometalation
  • Oxidative Addition
  • Reductive Elimination
  • Transmetalation
  • Electron Transfer
  • Beta-hydride elimination

Industrial Applications

Industrial Processes that include alkene derived polymers depends upon the organometallic catalyst. A process involving hydrogen depends upon a metal-based catalyst.

Several semiconductors are derived from a trimethyl antimony, trimethylindium, trimethylaluminum, and trimethylgallium. It is used in chemical reactions as well both as stoichiometric reagents and homogeneous catalysis.
