Structural kinetic rules governing the thermal decomposition of pyridine N-oxides
The Arrhenius parameters of the thermal composition of pyridine N-oxides in the liquid phase have been determined. The conclusion has been reached that the formation of an oxaziridine activated complex can be considered as the initial act of the thermolysis. A correlation has been found to exist between the rate constants of the thermal decomposition and the calculated values of the fractional electron charge at the oxygen of the N-oxide, and the length of the N- O bonds.
