A general synthetic route to dibenzoxanthenes has been developed using 1,4-diazaniumbicyclo[2.2.2]octane diacetate as a new bis ionic liquid under thermal and solvent free condition. This method provides several advantages such as a simple work-up, environmental friendliness and shorter reaction time along with high yields. All of the synthesized compounds were characterized by infrared spectroscopy, 1H and 13C spectroscopy and elemental analyses.
