Reaction of aldehydes with secondary amines
WebThere are many other nitrogenous nucleophiles that can react with aldehydes and ketones, for example hydroxylamine (NH 2 OH), or hydrazine (NH 2 NH 2) or a whole range of substituted hydrazines, all react with aldehydes and … WebAldehydes and ketones react with primary amines, in mildly acidic conditions, forming an imine (a Schiff base ). The reaction with secondary amines produces enamines: Just like the reaction with water and alcohols, this is also an addition reaction to the carbonyl group.
