Recyclable solid catalysts based on hydrogen-bond donor (HBD) groups have been rarely explored for the cycloaddition of CO2 to epoxides, despite their inherent advantages such as high efficiency and the absence of metal species. Herein, we report a covalent triazine framework (CTF) incorporating amide units as a recyclable organocatalyst for this reaction. The catalyst was readily synthesized via a condensation reaction between inexpensive and readily available precursors, melamine and dipicolinic acid, in dimethyl sulfoxide at 140 °C. Following structural characterization and confirmation of the CTF formation, its catalytic performance was first evaluated in the model reaction of CO2 with styrene oxide. Investigation of the reaction parameters revealed that the optimal conditions were 50 mg of CTF, 0.5 mol% tetrabutylammonium bromide (TBAB) as a co-catalyst, a CO2 pressure of 10 bar, and a temperature of 100 °C. Under these optimized conditions, a range of terminal epoxides was successfully converted into their corresponding cyclic carbonates in excellent yields. Furthermore, the catalyst demonstrated excellent recyclability, maintaining its catalytic activity without a significant loss in yield over six consecutive runs.
