In recent years, significant advancements have been made in the realm of organoboron catalysis for the homopolymerization of epoxides and the copolymerization of epoxides and other monomers. Nevertheless, the utilization of chiral organoboron catalysts for the stereoselective polymerization of epoxides is underdeveloped and highly needed. Herein, we present a suite of chiral bifunctional and binary organoboron catalysts to catalyze the homopolymerization of racemic epoxides in isotactic-enriched polyethers (62.1%m–84.8%m) with narrow dispersities. This article explores the effects of catalysts with different chemical structures and initiators as well as the reaction temperature and solvents on the stereoselective polymerization of epoxides, providing guidance for the upgrading of chiral organoboron catalysts and the design of new organocatalysts.

使用有机硼催化剂进行环氧化物的立体选择性聚合

近年来，有机硼催化环氧化物均聚以及环氧化物与其他单体共聚领域取得了重大进展。然而，用于环氧化物立体选择性聚合的手性有机硼催化剂的应用尚未开发且非常需要。在此，我们提出了一套手性双功能和二元有机硼催化剂，用于催化外消旋环氧化物在具有窄分散性的全同立构富集聚醚（62.1％m – 84.8％m）中的均聚。本文探讨了不同化学结构和引发剂的催化剂以及反应温度和溶剂对环氧化物立体选择性聚合的影响，为手性有机硼催化剂的升级和新型有机催化剂的设计提供指导。
