There’s a reason the “organo” comes first in “organometallic chemistry”—These catalysts usually the aid in the creation of new bonds in organic compounds, building up complex products from simple starting materials.

In these contexts, the terms acid and base typically refer to the thermodynamic propensity of a substance to give and accept hydrogen ions while the terms nucleophile and electrophile refer to a substance's kinetic propensity to react with carbon-based Lewis acids and bases, respectively.

This definition covers Brønsted-Lowry proton transfer reactions, but also includes reactions in which no proton transfer is involved.

Lewis acids are electron pair acceptors, while Lewis bases are donors. This concept explains reactions like the classic example between borane BH3 and NH3, resulting in a coordinate covalent bond. The Usanovich acid-base concept extends this by including oxidation-reduction reactions.

Most organic compounds are electrically neutral; they have no net charge, either positive or negative. However, certain bonds within a molecule, particularly the bonds in functional groups, are polar, which is a consequence of an unsymmetrical electron distribution in a bond due to the difference in electronegativity of the bonded atoms.

It is not a biological reaction, but nonetheless can serve as a convenient model to introduce some of the most important ideas about electrophilic reactions.

In an electrophilic substitution reaction, a pair of π-bonded electrons first attacks an electrophile - usually a carbocation species - and a proton is then abstracted from an adjacent carbon to reestablish the double bond, either in the original position or with isomerization.
