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 β versus DS β for both reactions gave good straight lines with isokinetic temperatures of 168

The results of ab initio SCF MO calculations at the Hartree-Fock (3-21G and 6-31G\*) and DFT levels (B3LYP/6-31G\*, B3LYP/6-311+ G\*\*) for 5-Γuoro-(5FP), 5-chloro-(5ClP) and 5-bromo-trans-penta-1,3-diene (5BrP) molecules and vibrational spectra (Raman and FTIR) of the corresponding liquid phases ar
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
