Using solvent-free conditions, non-toxic and inexpensive materials, simple and clean work-up, short reaction times and good yields of the products are the advantages of this method.}, number={4}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Khazdooz, Leila and Zarei, Amin and Hajipour, Abdol R. and Sheikhan, Nafisehsadat}, year={2024}, month={Feb.}, keywords={Methylimidazolium hydrogen sulfate, Pyrimidinone, Bronsted acidic ionic liquid, Biginelli-type reaction} }
