Oxidative ammonolysis of 3(4)-methyl- and 3,4-dimethylpyridines using vanadium oxide catalysts

Oxidative ammonolysis of 3(4)-methyl- and 3,4-dimethylpyridines using vanadium oxide catalyst doped with Cr2O3, SnO2, and ZrO2 was studied. The yields of nitriles and conversion of the starting compounds were found to depend on the CH-acidity of the latter in the gas phase. The possible mechanisms of the formation of pyridine-3,4-dicarboxylic acid imide at the oxidative ammonolysis of 3,4-dimethylpyridine was discussed. The relation between the activity of the modified catalysts and the proton affinity of the vanadyl oxygen calculated by the extended Hueckel method was established.

PYRIDAZINES CONDENSED WITH A HETERO RING, II. PYRIDO AMINOPYRIDAZINES, I. SEPARATION AND STRUCTURE DETERMINATION OF THE ISOMERIC MONOCHLORO COMPOUNDS OBTAINED BY HYDROLYSIS OF 1,4-DICHLOROPYRIDOPYRIDAZINE

The separation of the mixture of isomers 2 and 3, obtained by hydrolysis of 1,4-dichloropyrido pyridazine, was accomplished and the structures of the isomers (2: 1-Cl; 3:4-Cl) were verified by synthesis.Aminolysis of 2 and 3 yielded the hydroxy-ethylamino derivatives 4 and 5; a mixture of these compounds can also be synthesized from 2-tosyloxyethylcinchomeronic imide (20 -> 4, 5) in a good yield (84percent).
