Pyrazolotriazines were synthesized from pyrazolecarboxylic acid hydrazides and carbonyl compounds.Pyrazolecarboxylic acid N'-phenylhydrazide (1c) and formaldehyde gave not only the expected 4h but 5, respectively.The methyl substituted hydrazides with acetone afforded hydrazones, pyrazolotriazines or 13 depending on the position of the substituents.The reduction of both products yielded pyrazolecarboxylic acid hydrazides.
A MESOMERIC BETAIN PYRAZOLO-OXYDOTRIAZINIUM RING SYSTEM. 6-ALKYL-2-METHYL-PYRAZOLOTRIAZIN-6-IUM-4-OLATES, SYNTHESIS AND RING CLEAVAGE

A novel type of the mesomeric betain ring system was synthesized from pyrazolecarboxylic acid N'-alkyl-hydrazides by a simple method.The structure of the compounds was proved by spectroscopic methods and synthetic routs.The oxydotriazinium ring opened wit
