Abstract
Microwave-assisted quaternization of glycine (GLY) resulted in the synthesis of an efficient catalyst, quaternized glycine (QGLY), for the solventless synthesis of cyclic carbonates from epoxides and CO2 under mild reaction conditions. Density functional theory was used to simulate the synergistic influence of the COOH group and the halide ion of QGLY in enhancing the catalytic activity.
摘要
微波辅助甘氨酸（GLY）季铵化反应合成了一种高效催化剂，即季铵化甘氨酸（QGLY），可在温和的反应条件下，无需溶剂，由环氧化物和 CO2 合成环状碳酸酯。通过密度泛函理论模拟了 QGLY 中的 COOH 基团和卤素离子协同增强催化活性的影响。
