In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen. It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide. The intr… WebReactions of Primary Amines with Aldehydes and Ketones (review of Chapter 17) Reaction type: Nucleophilic Addition then Elimination Summary Primary amines, R-NH2 or ArNH2, undergo nucleophilic addition with aldehydes or ketones to give carbinolamines which then dehydrate to give substituted imines.

WebThis pathway is not available to aldehydes and ketones, but it dominates the reaction of carboxylic acid derivatives. The overall result is that when an amine (or any nucleophile) reacts with a carboxylic acid derivative the outcome is that the amine replaces the leaving group (a hydrogen is lost from the amine nitrogen too).
