The main advantages of this method are: (1) simplicity of the procedure, (2) solvent-free conditions, (3) availability of the starting materials, (4) high reaction rates and excellent yields, (5) reusability of the catalyst and (6) no column chromatographic of the products.}, number={4}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Shirini, Farhad and Koodehi, Tahereh Ghauri and Goli-Jolodar, Omid}, year={2024}, month={Feb.}, keywords={Phthalazine derivatives, Solvent-free conditions, Brönsted acidic ionic catalyst} }
