The reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. This method is also simple and inexpensive and leads to high yield of products in short reaction times.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Khodabakhshi, Saeed and Baghernejad, Mojtaba}, year={2024}, month={Feb.}, keywords={Water, Silica gel, Catalyst, Aldehyde, Biscoumarin} }
