Electrochemical production of novel products from 2,3-dimethylhydroquinone in the presence of some β-diketones

摘要

Electrochemical oxidation of 2,3-dimethylhydroquinone has been studied in the presence of β-diketones as nucleophiles in aqueous solution using cyclic voltam-metry and controlled-potential coulometry. The results indicate that the derivatives of 2,3-dimethylhydroquinone participate in a Michael addition reaction to form the corresponding benzofuran derivatives. The electrochemical synthesis has been successfully performed at pH 7.0 and E = 0.1 V versus an AglAgCllKCl (3 M) in an undivided cell in good yield and purity.
