Abstract
Abstract Electrochemical oxidation of catechol ( 1d ), 3-methylcatechol ( 1a ), 3-methoxycatechol ( 1b ) and 2,3-dihydroxybenzoic acid ( 1c ) in the presence of 4-hydroxycoumarin as nucleophile in aqueous solution has been studied using cyclic voltammetry and controlled-potential coulometry. The results indicate that ( 1a–1d ) participating in a 1,4 (Michael) addition reaction convert to coumestan derivatives ( 5a–5d ). The electrochemical synthesis of 5a–5d has been successfully performed in an undivided cell in good yield and purity.
