The present method was operationally simple and use of water as the reaction medium made the process environmentally benign.}, number={4}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Hosseini, Hadis and Ghazanfari, Dadkhoda and Nezamabadi, Vida}, year={2024}, month={Feb.}, keywords={Tetrahydrobenzo[b]pyran, Green media, Dihydropyrano[c]chromen, p-Dodecylbenzenesulfonic acid (DBSA)} }
