The article was written by Dinh Dang, Minh-Huy; Ho Thuy Nguyen, Linh; Thi Thu Nguyen, Trang; Xuan Dat Mai, Ngoc; Hoang Tran, Phuong; Le Hoang Doan, Tan. The article contains the following contents:
In this work, a sulfate-functionalized Hf-cluster-based metal-organic framework was prepared via sulfation of a Hf-MOF, named Hf-BTC, constructed by Hf6 clusters and 1,3,5-tricarboxylate linkers. The Hf-BTC-SO4 material was consequently demonstrated to be an efficiently reusable superacid catalyst for a one-pot three-component reaction of pyrimido[1,2-a]benzimidazoles synthesis. The reaction catalyzed by the sulfated Hf-BTC could be carried out under mild and solvent-free conditions and give superior performance in a wide range of substrates. According to detailed investigation, the good catalytic performance of the sulfated-functionalized MOF likely originates from the high-porosity framework and the high active sites of the functionalized clusters. Importantly, the catalyst was easy to recover and reuse the functionalized framework several times with minor changes in catalytic efficiency. The experimental process involved the reaction of 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Recommanded Product: 934-32-7)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Recommanded Product: 934-32-7
