Abstract
|
Electrosynthesis of main organic compounds has been extensively employed as a synthetic method in a variety of chemical transformations due to its unique properties such as eco‐friendly nature, direct and short‐cut synthetic route, high current efficiency values, high selectivity and sustainability of the reactions [1]. Phenoxazine is a heterocyclic compound that its structure consists of an oxazine fused to two benzene rings. In recent years, medicinal properties of phenoxazine derivatives have widely been investigated and were shown to be effective material as antitumor, antileukemia and antimicrobial [2]. 4-Amino-14H-dibenzo[a,h]phenoxazin-11-ol (Fig. 1) as a new phenoxazine derivative has been synthesized by a green one-pot method and structurally characterized by spectroscopic analysis. The electrochemical oxidation of 1,5- diaminonaphthalene (1,5-DAN) was studied and evidence for generation of naphthalene-1,5-diimine (1,5-DANox) was obtained. Our data are also show that 1,5- DANoxcan serve as a Michael acceptor in the reaction with starting molecular (1,5- DAN) and converts to 4-amino-14H-dibenzo[a,h]phenoxazin-11-ol. Spectroscopic characterization and voltammetry results have allowed us to propose ECE mechanism for the electrochemical oxidation pathway.
