Simple Operation

Novel SO3H-functionalized ionic liquids were successfully applied as catalysts for synthesis of xanthenediones under microwave irradiation in Aqueous. Various types of Xanthenes were provided in 90-97% yields using the catalytic system of [(HSO3-p)2im][CF3SO3]/H2O. The products could be conveniently separated from the reaction mixture by filtration and the dissolved catalyst could be reused without any treatment, which of the separation process was performed in water without using any organic solvents. The method not only has the adventages of shrot time and simple operation, but also is environmentally friendly.
