Synthesis of pyridine bases by way of relatively simple transformations with use of cheaper and available raw, is an actual problem. In this aspect the method in which the reactions of hydro-carbons oxidation are induced by nitrous oxide, is of scientific and practical interest. In the present work, the authors report the results of the experiments coherent-synchronized oxidation of pyridine with nitrous oxide to 2,2- and 2,3-dipyridyle.

The regions of the selective oxidation of the the production of 4-vinylpyridine, 4-vinylpyridine coherent-synchronized mechanism is suggested for 4-ethylpyridine and piperidine. The HO^＊2 radical plays 4-ethylpyridine and piperidine have been found, and the optimal conditions for N-monoxide and pyridine have been determined. The most probable hydrogen peroxide decomposition and the free-radical chain oxidation of the key role in this mechanism.

The interfering kinetics of the coherent synchronous reactions of hydrogen peroxide decomposition and the oxidation of pyridine derivatives have been studied experimentally. The regions of the selective oxidation of the pyridine derivatives have been found, and the optimal conditions for the production of4-vynilpyridine, 4-vynilpyridine N-monoxide, 2, 2-dipyridyl, and pyridine have been determined. The most probable synchronization mechanism is suggested for hydrogen peroxide decomposition and the free-radical chain oxidation of pyridine derivatives. The HO2 -radical plays the key role in this mechanism. The activation energies are calculated for the elementary steps of 4-ethylpyridine dehydrogenation.

关键词： Free radical coherent synchronized conjugation N-monooxidation determinant.
