Silica sulfuric acid as an efficient and reusable heterogeneous catalyst has been used for the preparation of amidines 2 from formimidate 1 through reaction with aromatic amines at room temperature and in good to excellent yields. All these derivatives were fully characterized by spectroscopic data.}, number={1}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Shirini, Farhad and Shirini, Farhad and Tavakoli, Fatamah}, year={2024}, month={Feb.}, keywords={Aiaminomaleonitrile.
