3-bromo-1,1,1-trifluoro-2-propanol (3-BTFP) in combination with n-butylammonium iodide (TBAI) was proved to be an efficient organocatalyst for chemical fixation of CO₂ with various epoxides to the respective cyclic carbonates. A possible reaction mechanism was proposed wherein 3-BTFP activated epoxide through hydrogen bonding interaction. This mechanism is revealed by the results of FT-IR spectra and ¹H NMR titration, and the synergetic effect functioned by 3-BTFP and TBAI ensures the reaction proceeding effectively. Herein, 3-BTFP represents a commercially available, stable and metal-free hydrogen-bonding donor for CO₂ transformation, which has a potential application for the large-scale synthesis of cyclic carbonates.

3-溴1,1,1-三氟-2-丙醇（3-BTFP）与正丁基碘化铵（TBAI）组合被证明是一种有效的有机催化剂，用于将CO ₂与各种环氧化物化学固定在各自的环上碳酸盐。提出了一种可能的反应机理，其中3-BTFP通过氢键相互作用激活了环氧化物。FT-IR光谱和¹ H NMR滴定的结果揭示了该机理，并且3-BTFP和TBAI发挥的协同作用确保了反应有效地进行。在此，3-BTFP代表用于CO ₂转化的可商购的，稳定且无金属的氢键供体，其对于大规模合成环状碳酸酯具有潜在的应用。
