摘要

设计、合成了一系列新型染料基有机催化剂，并在温和反应条件下（45°C, 10 bar CO2）将CO2与氧化苯乙烯环加成生成碳酸苯乙烯。通过调整改性染料的酸强度和-OH官能团的几何形状，可以生成具有增强催化活性的定制双功能催化剂（rhb -乙基- phoh - i）。

Bifunctional dye-based organocatalysts with enhanced activity in the conversion of CO2 into cyclic carbonates†

A series of novel dye-based organocatalysts was designed, synthesised and tested in the cycloaddition of CO₂ to styrene oxide yielding styrene carbonate under mild reaction conditions (45 °C, 10 bar CO₂). Tuning the acid strength and the geometry of the –OH functional group in the modified dyes allowed the generation of a tailored bifunctional catalyst (RhB-Ethyl-PhOH-I) with enhanced catalytic activity.
