SYNTHESIS OF 2,3-DIHYDROBENZOFURAN DERIVATIVES VIA ELECTRON TRANSFER REACTION CATALYZED BY IRON(III)-SALT IN AN IONIC LIQUID SOLVENT SYSTEM

摘要

The ferric ion salt-catalyzed [2+3]cycloaddition of styrene derivatives with quinone was carried out in various types of ionic liquids. The reaction was significantly dependent on the counter anion of the ionic liquids and the UV spectra change of the reaction was looked at to discuss the origin of the remarkable acceleration by the ionic liquid solvent system.
