ELECTROCHEMICAL INVESTIGATIONS ON HYDRAZONO COMPOUNDS

Electrochemical reduction of ethyl-2-arylhydrazono-3-phenyl-propanoate -1, 3-dione and 1,5-diphenyl-3-benzoylformazan was studied at d.m.e. a nd G.C. electrodes. Ethyl-2-arylhydazono-3-phenylpropanoate-1,3-dione gave one, four electron, diffusion-controlled, irreversible wave, wher eas 1,5-diphenyl-3-benzoylformazan gave two reduction waves correspond ing to the reduction of azo and hydrazono groups. Products of controll ed potential electrolysis were successfully identified and a mechanism postulated The effect of ionic-strength and solvent composition for t he reduction of hydrazono group is also reported.
