A chemist draws the structure of an enamine on a whiteboard.

Definition

1. Noun:
   • An amine containing the double bond linkage -C=C-N-: An enamine is a type of organic compound. It is formed by the reaction of a carbonyl compound (like an aldehyde or ketone) with a secondary amine, resulting in a structure where a nitrogen atom is bonded to a carbon atom that is part of a carbon-carbon double bond.

Usage Examples

• Noun:
  • The chemist synthesized an enamine as a key intermediate in the reaction.
  • Enamine formation is a useful method for temporarily protecting a carbonyl group.

Advanced Usage

• In organic synthesis: Enamines are valuable intermediates in organic chemistry, particularly in the Stork enamine alkylation reaction, where they are used to add alkyl groups to the alpha position of carbonyl compounds.
  • The researcher utilized an enamine to selectively alkylate the ketone.

Variants and Related Words

• Imine (n): A related compound with the structure -C=N-, formed from a carbonyl and a primary amine.
  • An imine is another important class of compounds derived from carbonyls and amines.

Synonyms

• Aminoalkene: A less common synonym describing the same functional group (an amine linked to an alkene).

Related Phrases

• Enamine hydrolysis: The process of converting an enamine back into its parent carbonyl compound and amine.
  • After the alkylation step, enamine hydrolysis yielded the desired product.
