The general structure of an enamine

An enamine is an unsaturated compound derived by the reaction of an aldehyde or ketone with a secondary amine followed by loss of H₂O. In Chemistry, saturation has five different meanings In Physical chemistry, saturation is the point at which a Solution of a substance An aldehyde is an organic compound containing a terminal Carbonyl group. A ketone (pronounced as key tone) is either the Functional group characterized by a Carbonyl group (O=C linked to two other Carbon atoms or Amines are Organic compounds and Functional groups that contain a basic Nitrogen Atom with a Lone pair.

The word "enamine" is apparently derived from the prefix en-, used as the suffix of alkene, and the root amine. In Organic chemistry, an alkene, olefin, or olefine is an unsaturated Chemical compound containing at least one Carbon Amines are Organic compounds and Functional groups that contain a basic Nitrogen Atom with a Lone pair. Compare with enol, which is a molecule containing both alkene (en-) and alcohol (-ol). Enols (also known as alkenols) are Alkenes with a Hydroxyl group affixed to one of the carbon atoms composing the Double bond. In Organic chemistry, an alkene, olefin, or olefine is an unsaturated Chemical compound containing at least one Carbon In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon

If one of the nitrogen substituents is H, it is the tautomeric form of an imine. Tautomers are Organic compounds that are interconvertible by a Chemical reaction called tautomerization. An imine is a Functional group or Chemical compound containing a Carbon – Nitrogen Double bond. This usually will rearrange to the imine; however there are several exceptions (such as aniline). Aniline, phenylamine or aminobenzene is an Organic compound with the formula C6H7N The enamine-imine tautormerism may be considered analogous to the keto-enol tautomerism. In Organic chemistry, keto-enol Tautomerism refers to a Chemical equilibrium between a keto form (a Ketone or an Aldehyde In both cases, a hydrogen atom switches its location between the heteroatom (oxygen or nitrogen) and the second carbon atom.
