Abstract

Herein, the six-membered sulfur-containing cyclic carbonates was successfully synthesized from d- and l-xylose through an environmental friendly process by employing carbonyl sulfide (COS) as a sustainable C1-carbonation agent. The ring-opening polymerization of the monomers were rapidly initiated by bifunctional organocatalysts and alkali metal alkoxides, respectively, under ambient reaction conditions. The resultant sulfur-containing polycarbonates exhibit high-temperature resistance and good optical properties. This work furnishes an original and practical strategy for utilizing COS as a sulfur feedstock in biopolymer synthesis.

以木糖和羰基硫化物为原料合成可持续含硫聚碳酸酯
本研究以羰基硫醚(COS)为可持续碳酸化剂,以d-木糖和l-木糖为原料,通过环境友好的工艺合成了六元含硫环碳酸酯。在常温条件下,双功能有机催化剂和碱金属醇氧化物分别快速引发了单体的开环聚合。所得的含硫聚碳酸酯具有耐高温性能和良好的光学性能。这项工作为利用COS作为生物聚合物合成中的硫原料提供了一种新颖而实用的策略。
