LI. Synthesis of formazans based on N-arylquinaldinium salts and their conversion into tetrazolium salts

  • 25 Accesses


The coupling of 1-arylquinaldinium salts with diazonium salts has given a number of formazans of symmetrical structure with a 1-arylquinoline residue attached to the formazyl carbon atom. Unsymmetrical formazans have been synthesized by coupling the phenylhydrazone of 2-formyl-1-phenylquinolinium perchlorate with diazonium salts. The oxidation of the formazans has given tetrazolium salts.
