Succinamic acids. Part II. Anhydrides as intermediates in the aminolysis of N-alkylanilic acids in toluene
Abstract
N-Alkylanilic acids are shown to undergo exchange with anilines in a reaction involving thermal dissociation of the acids to the corresponding anhydride and N-alkylaniline. The anhydride can be formed either by a unimolecular process or by a bimolecular, carboxylic acid-catalysed reaction.
