The ring-opening of epoxides plays a crucial role in synthesizing antitumoral pharmaceuticals and fine chemicals, the key lies rational design highly efficient catalysts. Herein, by using 4-(2-carboxyethenyl)benzoic acid 1,10-phenanthroline (phen) hydrate as mixed ligands, new Co(II)-based porous metal-organic framework (Co-CBA) has been synthesized via solvothermal reaction. Structural analysis revealed that Co-CBA features unique trinuclear clusters building blocks, which link with ligands to form sequentially two-dimensional network. appropriate pore channels high density metal active facilitate its exceptional catalytic performance heterogeneous catalyst reaction epoxy chloropropane methanol. Under optimal conditions, this achieves >99% conversion selectivity for target product 1-chloro-3-methoxypropan-2-ol within 28 h. In addition, also displays excellent substrate compatibility, outstanding reusability, robust structural stability after catalysis. A plausible pathway proposed.
