“…The electrochemistry of heterocyclic compounds with nitrogen heteroatom has been extensively studied [1][2][3][4][5][6][7][8][9]. In spite of great importance and wide uses of the heterocyclic aromatic compounds with oxygen or sulphur atoms, it is rare to find an attempt to study their electrochemical redox characteristics.…”

Abstract:The redox characteristics of some substituted chromene derivatives has been investigated in different nonaqueous solvents such as, 1,2-dichloroethane (DCE), dichloromethane (DCM) and acetonitrile (AN) using 0.1mol dm -3 tetrabutylammonium perchlorate (TBAP) as a supporting electrolyte at platinum, gold and glassy carbon electrodes, using cyclic voltammetry. Through controlled potential electrolysis (CPE), the product of oxidation and reduction can be separated and identified. The product of oxidation was found to be the corresponding bis-compound. On the other hand, the reduction occurs in a single two electron process to give the dianion, which abstracts protons to saturate the (-C=O) bond. The effect of substituents on the redox mode of an electroactive site has also been studied.
