1,4-diazanium-bicyclo[2.2.2]octane diacetate: As an effective, new and reusable media for the synthesis of 14-aryl-14H-dibenzo [a,j]xanthenes

Leila Zare Fekri, Hajar Saeedi Fard


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