Abstrakt: In this study, [DABCO](SO 3 H) 2 CuCl 4 as a novel DABCO-based molten salt with dual acidic functionality (Brønsted and Lewis) has been synthesized, characterized and used as a high-performance catalyst in the one-pot synthesis of 3,4-dihydropyrimidine and polyhydroquinoline derivatives. The identification of this catalyst was accomplished by using techniques such as infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermo gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray (EDS) spectroscopy. Excellent efficiency, short reaction times, a simple working method and also use of a recyclable catalyst are the considerable advantages of this process.
