2-chloro-N-phenacylpyridinium salts, diazonium salts, thiazolo[2, 3-c][1, 2, 4]triazol-4-ium salt, [1, 4]triazolo[4, 3-a]-pyridinium salts, cyclizationAbstract
The reaction of 2-chloro-N-phenacylpyridinium salts with diazonium salts in the presence of bases was studied for the first time. It was demonstrated that this reaction leads to the formation of [1,2,4]triazolo[4,3-a]pyridinium salts. It was shown that substitution of the pyridine with a thiazole moiety leads to a similar cyclization.
