摘要

Carbon dioxide as a C1 building block to synthesize α-alkylidene cyclic carbonates is an environmental and sustainable approach. In this work, we designed and synthesized a multifunctional magnetic MOF nanocatalyst CuFe2O4@SiO2@MOF-5, which could realize the carboxylic cyclization of CO2 and propargylic alcohols into α-alkylidene cyclic carbonates in high to excellent yields under mild reaction conditions. More importantly, the nanocatalyst CuFe2O4@SiO2@MOF-5 exhibited excellent reusability and could be recycled at least six times retaining its excellent catalytic activity as well as chemical stability. These findings may be useful for the rational design of heterogeneous and recyclable routes for the catalytic conversion of CO2 to valuable chemicals.
