THERMAL HETEROCYCLIZATION OF METHYL ARYL KETAZINES. III. REACTIONS OF THE TAUTOMERIC FORM OF THE AZINE

The thermal reactions of methyl allyl ketazines (R= C6H5, 4-CH3C6H4, 4-CH3OC6H4, α-C10H7) in the region 320-350 deg C represent rearrangements to phthalazine and, to a lesser degree, indazole derivatives.The decomposition of these compounds and of the other cyclization products (pyridazines, pyrazoles, benzodiazepines), which determine the composition of the pyrolyzate at lower temperatures, leads to the formation of aromatic nitriles.This result rules out the formation of the latter by a mechanism of radical cleavage of the N-N bond in the azines of the aliphatic-aromatic series.A direct analogy was found between thermolysis and dissociative ionization, and this made it possible to predict the thermal reactions by means of mass-spectral data.
