Herein, a novel approach is reported for the synthesis of medium‐ and long‐chain aliphatic polyethers 2 based on the GaBr3‐catalysed reduction of polyesters 1 with TMDS as the reducing agent. Thus, various linear and branched aliphatic polyesters 1 were prepared and systematically investigated for this reduction strategy, demonstrating the applicability and versatility of this new polyether synthesis
本文报道了一种新颖的方法,该方法基于以TMDS为还原剂的GaBr 3催化的聚酯1的还原反应,合成中链和长链脂族聚醚2。因此,制备了各种直链和支链脂族聚酯1并针对该还原策略进行了系统研究,证明了这种新的聚醚合成方案的适用性和多功能性。中期和长链链聚醚分别从各自的聚酯没有或有轻微的链降解获得,而短链聚酯,如聚-升-丙交酯1 I和聚[([R)-3-羟基丁酸酯] 1焦耳,显示出主要的链降解。以这种方式,获得并研究了先前不可用和不常见的聚醚。
