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.[1][2][3] It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide.[4] The intramolecular reaction was not reported until 1991[5] but has become important in the synthesis of natural products.[6] The reaction is effective with carboxylic acids to give amines (above), and with ketones to give amides (below).
