Described is a robust platform for the synthesis of a large diversity of novel functional CO -sourced polymers by exploiting the regiocontrolled ring-opening of α-alkylidene carbonates by various nucleophiles. The reactivity of α-alkylidene carbonates is dictated by the exocyclic olefinic group. The polyaddition of CO -sourced bis(α-alkylidene carbonate)s (bis-αCCs) with primary and secondary diamines provides novel regioregular functional poly(urethane)s. The reactivity of bis-αCCs is also exploited for producing new poly(β-oxo-carbonate)s by organocatalyzed polyaddition with a diol. This synthesis platform provides new functional variants of world-class leading polymer families (polyurethanes, polycarbonates) and valorizes CO as a chemical feedstock.
描述了一种通过利用各种亲核试剂对α-亚烷基碳酸酯的区域控制开环来合成大量新型功能 CO 源聚合物的强大平台。α-亚烷基碳酸酯的反应性由环外烯烃基团决定。CO 源双（α-亚烷基碳酸酯）（双-αCC）与伯胺和仲二胺的加成提供了新型的区域规整功能型聚（尿烷）。双-αCC 的反应性也可用于通过与二醇的有机催化加成来生产新型的聚（β-氧代碳酸酯）。该合成平台为世界级领先聚合物家族（聚氨酯、聚碳酸酯）提供了新的功能变体，并使 CO 成为一种有价值的化学原料。
