The kinetics of the reactions of aroyl chlorides with N-methylarylamines in benzene were studied with crossed variation in the structures of the reagents.The attainment of the isoparametric point with respect to the structure of the N-methylarylamine was demonstrated by crossed correlation.The energy parameters for the reactions of benzoyl chloride with N-methylarylamines are 10percent lower than those obtained for primary arylamines.The higher reactivity of the N-methylarylamines compared with the corresponding primary arylamines is due to the resonance stabilization of the transition state.

The benzoylation of 3,5-dinitroaniline and N-methyl-3,5-dinitroaniline, catalyzed by tetrabutylammonium chloride in benzene, was investigated in the range of 283-328 deg K.The activation energy of the catalytic process includes the enthalpy of formation of the H complex between the arylamine and tetrabutylammonium chloride and the activation energy of its reaction with benzoyl chloride.
