The kinetics of the reactions of aroyl bromides with primary arylamines in benzene were studied at 10, 25, 40, and 55 deg C.The effects of factors (temperature, the structure of the aroyl bromides and primary arylamines) varied separately and in pairs and also the joint effect of the three factors on the process rate were assessed quantitatively.The joint effect of the structure of the primary arylamines and the temperature on the reactivity of the system is nonadditive, and the effect of the structure of the aroyl bromides and temperature is additive.The influence of the varied parameters on the nature of the translation states in the reactions is discussed.

Rates were measured for the reactions of aroyl bromides with primary arylamines in 1:1 chlorobenzene-cyclohexane at 25 deg C.The kinetic data were treated by the Hammett-Taft equations and cross correlation.This is the first reported transition through an isoparametric point relative to the structure of the nucleophile accompanied by inversion of the sign of the sensitivity parameter relative to the substrate structure in the aroyl bromide-primary arylamine reaction system.The results of the cross correlation analysis were interpreted on the basis of a concerted mechanism involving nucleophilic substitution at the carbonyl carbon atom.The relationship between the reactivity of the system studied and its selectivity was examined.

Rate constants for the reactions of ω-bromo-2-acetonaphthone with aniline and pyridine in various protic and aprotic solvents have been determined at three temperatures.The rates of reaction with pyridine in simple alcohols are less than those with aniline.Values of Hammet ρ-constant have been obtained for the reactions with substituted anilines in a few solvents.Multiple correlation of log k40 deg C for the reaction with aniline in various alcohols employing several solvent parameters is highly successful.
