A metal-carbon bond is found in an organometallic molecule. The study of molecules containing metal-carbon bonds, as well as reactions involving them, is known as organometallic (OM) chemistry. The metal-carbon bond may be temporary or transient, but if one exists during a reaction or in a compound of interest, it should be investigated further. Organometallics are also essential in other disciplines of chemistry, such as biological and analytical chemistry.
Organocatalysis is a type of catalysis in which an organic (non-metallic) substance serves as the catalyst in a chemical reaction. The catalysts work by forming transient covalent interactions in the case of enamine and iminium catalysis, as well as non-covalent interactions in the case of hydrogen bonding catalysis.
The study of the structures and biological activities of inorganic biological substances, that is, those that do not include carbon, such as metals, is known as bioinorganic chemistry. In biological chemistry, bioinorganic chemistry is vital for understanding the implications of electron-transfer proteins, substrate bindings and activation, atom and group transfer chemistry, and metal characteristics.
