对丙烯基茴香醚的直接电氧化活化
Direct electro-oxidation ofp-propenyl anisole
摘要
Abstract
Direct electro-oxidation ofp-propenyl anisole(p-PA) in acetonitrile aqueous solutions was studied by cyclic voltammetry (CV), controlled potential electrolysis and chronoamperometry. The effect of water content, scan rate, temperature, reactant concentration, electrolysis potential and electrode on activation of C═C bond were studied. The results showed that electro-oxidation ofp-PA in acetonitrile aqueous solutions was an irreversible process, which was mainly diffusion-controlled with the diffusion coefficient (D) of 2.53×10?6 cm2·s?1. The major direct electro-oxidation product ofp-PA was p-methoxybenzaldehyde (p-MBA). At 20% water content, the yield ofp-MBA could be improved to 93% and almost complete conversion of reactant on graphite rod electrode at 25℃ in an undivided electrolytic cell.关键词
