Abstract
Abstract Electrochemical oxidation of catechols ( 1a – d ) has been studied in the presence of N , N -dimethylethylendiamine ( 3 ) as a nucleophile in aqueous solutions, using cyclic voltammetry, constant-current coulometry and controlled-potential coulometry. The results indicate that the quinones derived from catechols ( 2a – d ) participate in Michael addition reactions with N , N ′-dimethylethylendiamine ( 3 ) via the ECECE mechanism to form the corresponding quinoxalinedione derivatives ( 6a – c ).
