A cholic acid-based bis-primary amine is capable of promoting the insertion of CO2 into epoxides with the cooperative aid of an iodide anion. This framework is transformed in situ into a bis-carbamic acid. The latter is the active catalytic species, operating through H-bonding interactions. Our system works with complete atom economy, under solvent-free, metal-free, and mild conditions. Also, it can

氨基甲酸。后者是通过H键相互作用而起作用的活性催化物质。我们的系统在无溶剂,无
金属和温和的条件下具有完全的原子经济性。另外,它可以回收利用。
