(organic chemistry) Any of a class of organic nitrogen compounds having the general formula R2C=NR; they are tautomeric with enamines.
(organic chemistry) Any of a class of unsaturated nitrogen compounds, having the general formula R2C=C(R)-NR2, prepared by the condensation reaction of an aldehyde or ketone with an secondary amine; they are the tautomeric forms of imines.
An imine ( or ) is a functional group or chemical compound containing a carbon–nitrogen double bond. The nitrogen atom can be attached to a hydrogen (H) or an organic group (R).
an amine containing the double bond linkage -C=C-N-
An enamine is an unsaturated compound derived by the condensation of an aldehyde or ketone with a secondary amine. Enamines are versatile intermediates.
