The reaction of diphenylketene p-tolylimine with carboxylic acids in aprotic organic solvents is accelerated by primary arylamines.The reaction rate is described by overall kinetic equation including calalytic and noncatalytic path.Additions of pyridine greatly retard the reaction.The proposal according to which the catalytic reaction takes place through a cyclic transition state, formed from the ketene imine and the complex of the carboxylic acid with the amine, was substantiated.
