摘要: Polystyrene-supported hydroquinone (PS-HQ) is presented as an in situ polymeric cocatalyst to replace polystyrene-supported benzoquinone (PS-BQ) in the PdCl2-catalyzed acetalization of methyl acrylate with methanol in supercritical carbon dioxide (scCO2) under oxygen atmosphere. Due to deletion of H2O2 oxidation step, PS-HQ is more convenient and relatively inexpensive.
