摘要: These activities, combined with diverse chemicalbehavior make quinones attractive targets in organic syn-thesis.The removal of volatile solvents reac-tions is the most important goal green chemistry. One ofthe efficient protocols to reach this aim replacementof ionic liquids possessing lowvolatility, high thermal stability, non-flammability, recycl-ability and unique catalytic activity. During recent years,ionic have attracted interest as environmentallybenign reagents due their favorable properties avariety reactions been successful usingionic liquids.
