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 -45ยฐC. The data show that k 3-NO 2 /k 5-NO 2 ratios are less tha

The kinetics of the reaction of 2-chloro-3-nitropyridine (ortho-like) and 2-chloro-5-nitropyridine (para-like) with a series of aryloxide ions were studied in methanol at different temperatures. Plots of DH โ‰  versus DS โ‰  for both reactions gave good straight lines with isokinetic temperatures of 168

The reaction rates of 2-chloro-3,5-dinitropyridine 1 with a series of arylthiolates 2a-h in methanol have been measured at 25ยฐC. The products are the corresponding 2-thioaryl-3,5-dinitropyridine 3a-h. Good Hammett correlation with value ฯช1.19 was obtained suggesting an elimination-addition mechanism
