WebThe main distinction between imine and enamine is that imine has a C=N bond while enamine has a C-N bond. Imines resemble carbonyls and are generated when a primary amine (or ammonia) reacts with a carbonyl-containing acid (H +, H 3 O + ). In its most basic form, it resembles a carbonyl with a double bond to nitrogen rather than oxygen. WebScripps Research
