Abstract
The redox characteristics of some substituted chromene derivatives has been investigated in different nonaque- ous 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 sepa- rated 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.
