Abstract:


A novel room temperature dicationic ionic liquid, namely 1, 1’-sulfinyldiethylammonium bis (hydrogen sulfate), was prepared and characterized by 1H NMR, 13C NMR, and FT-IR as well as Hammett acidity function and used as a powerful and recyclable catalyst for the synthesis of xanthenediones with high to excellent yields as well as short reaction times under solvent-free conditions.

Keywords:

dicationic ionic liquid, solvent-free conditions, xanthenediones
