Enamins - Amines where the amino group (NR / 3; R = alkyl or hydrogen) is attached directly to the carbon atom bonded to the other carbon atom.
The first (C = C-NH2) and the secondary (C = C-NR2) primary epnines are inherently unstable and can not be obtained purely because they undergo a self- Tertiary Enamins (C = C-NR2) are durable. They are obtained in the same reaction as the imine, ie by the amination of ketones and aldehydes with secondary amine: Tertiary Enamins were first received by Gilbert Stork in 1954. These compounds are used in organic synthesis for the alkylation and acetylation of aldehydes and ketones.
