electrochemical study of phenylhydrazine and its application in the electrosynthesis of new phenylhydrazine derivatives

Abstract: hydrazine (hz) and its derivatives are widely used in agricultural chemicals (pesticides), chemical blowing agents, pharmaceutical intermediates, photography chemicals, and boiler water treatment in hot-water heating systems for corrosion control [1].moreover, hz salts and its derivatives are used as rocket fuel, gas generators, and explosives [2]. phenylhydrazine is the first hydrazine derivative to be used to prepare indoles by the synthesis of indole fisher, which is used as an intermediate in the synthesis of various dyes and drugs. this molecule is also used to induce acute hemolytic anemia in animal models. in this work, the electrochemical oxidation of phenylhydrazine in the presence of ß-naphthol as a nucleophile has been investigated. based on the results which obtained from the voltammetric data, the electrolysis was performed under the constant current method in order in an aqueous buffered solution (ph = 8.0, c = 0.2 m h3po4) to synthesis of new product. product formation was confirmed by using ir, ms and nmr spectra
