The conversion of CO₂ to cyclic carbonates via cycloaddition with epoxides is a 100% atom economy reaction, but necessitates the use of a catalyst to be economically viable. In this work, a microporous metal-organic framework (MOF) Ni(HBTC)(4,4’-bipy) has been synthesized and its synergistic catalytic activity with a co-catalyst containing strong nucleophilic anion has been studied for the solventless cycloaddition of CO₂ with epoxides under mild reaction conditions. The structure of Ni(HBTC)(4,4’-bipy) consists of honeycomb grid layers built by Ni²⁺ ions and BTC groups, and are linked by 4,4’-bipy pillars to form a 3D highly porous framework. Significant conversion of various epoxides was obtained with excellent selectivity toward the desired five-membered cyclic carbonates.
