| Abstract: | Benzofuranone derivatives were synthesized from o-hydroxyaromatic ketones in KOH/MeOH solution using ionic liquid supported(diacetoxyiodo)benzene{1-(4-diacetoxyiodobenzyl)-3-methylimidazolium tetrafluoroboratedibmim]+} as an oxidant.The structures were characterized by 1H NMR,13C NMR,IR,MS and elemental analysis.Compared with diacetoxyiodobenzene,dibmim]+ exhibited more oxidizability.The reaction mechanism was proposed. |
