- Abstract
The coupling of 3-alkyl-4-(methoxyphenyl)-1 H-pyrazole-5-diazonium salts with acetylacetone followed by cyclization of the formed heterylhydrazones resulted in pyrazolo[5,1- c][1,2,4]triazines. The 4-(3,4-dimethoxyphenyl)-3-methyl-1 H-pyrazole-5-diazonium salt was not involved into a similar reaction but suffered an intramolecular azo coupling giving pyrazolo[3,4- c]-cinnoline.
