The heats of acyl exchange reactions between a number of N-, O-acyl salts and 4-dimethylaminopyridine N-oxide and 4-dimethylaminopyridine were measured in solutions of aprotic solvents. The spectroscopic characteristics and the electrolytic dissociation constants of the salts were obtained and the thermochemical and structural data compared. Changes in the heats under structural actions are satisfactorily described by a two-parameter correlation equation including the ionization potentials of bases and the integrated intensities of salt C=O stretching vibrations as variables.
