WebDifference between Imine and Enamine. 1. An imine is an organic compound consisting of a C=N double bond. An enamine is an unsaturated organic compound with an amine … An enamine is an unsaturated compound derived by the condensation of an aldehyde or ketone with a secondary amine. Enamines are versatile intermediates. The word "enamine" is derived from the affix en-, used as the suffix of alkene, and the root amine. This can be compared with enol, which is a functional … See more Enamines are labile and therefore chemically useful moieties which can be easily produced from commercially available starting reagents. A common route for enamine production is via an acid-catalyzed … See more Enamines act as nucleophiles that require less acid/base activation for reactivity than their enolate counterparts. They have also been shown to offer … See more • Enders SAMP/RAMP hydrazone-alkylation reaction • Hajos–Parrish–Eder–Sauer–Wiechert reaction See more Alkylation Even though enamines are more nucleophilic than their enol counterparts, they can still react selectively, rendering them useful for alkylation reactions.
