The kinetics of the reactions of 2-chloro-3-nitropyridine (ortho-like) and 5-nitro ( para-like) isomer with morpholine and piperidine were studied in methanol and benzene at several amine concentrations and temperatures in the range 25 -45Β°C. The data show that k 3-NO 2 /k 5-NO 2 ratios are less tha
