## Abstract The kinetics and mechanism of the nucleophilic substitution reactions of __p__‐chlorophenyl aryl chlorophosphates (2) with anilines are investigated in acetonitrile at 55°C. Relatively large magnitudes of ρ~X~ and β~X~ values are indicative of a large degree of bond making in the TS. Sm

Substitution reactions of some parasubstituted anilines with 2-chloro-5nitropyridine and 2-bromo-5-nitropyridine were carried out conductometrically in dimethylsulfoxide/acetonitrile mixtures. The correlation of second order rate constants with Hammett's substituent constants yields a fairly linear
## Abstract We report a kinetic study on the reactions of secondary alicyclic amines toward 4‐nitrophenyl, 2,4‐dinitrophenyl, and 2,4,6‐trinitrophenyl acetates (**1, 2**, and **3**) in ethanol/water mixtures of different compositions. It is found that (i) the intermediate in the reaction of **1** i
