Abstract

The synthesis, studies on structure of some water soluble formazane derivatives. Several 1,5-diaryl-3-heterocyclic water soluble formazanes have been synthesiszed by the reaction at 0-5C of aryldiazonium hydrochloride with aryhidrazone which have been prepared by the condensation of arylandehydes with arylhidrazines. Its structure has been indentified by IR, UV, and mass spectra. The band of complexes with lengths abouut 60-180nm, compared to the correspoding formazanes in water solvent.
