The magnetically retrievable and sustainable catalyst was investigated in the reaction of aldehyde and o-aminophenol for the synthesis of benzoxazoles. The reactions occurred in water and produced the corresponding products in high yields. The catalyst could be readily separated by an external magnet and showed excellent reusability without significant loss of its activity.}, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Sayyahi, Mona and Gorjizadeh, Maryam and Sayyahi, Soheil}, year={2024}, month={Feb.}, keywords={Reusability., Solid acid catalyst, Magnetic nanoparticles, Benzoxazoles} }
