Abstract

We report the rationalised design of aluminium initiators and their application for ROP of rac-lactide (rac-LA). A very minor change to the ligand backbone (imine reduction) to give secondary amines was found to have a dramatic effect on activity and selectivity with isotactic PLA being realised.

摘要

我们报道了铝引发剂的合理设计及其在消旋丙交酯(rac-LA)的开环聚合反应中的应用。研究发现,对配体主链进行非常微小的改变(亚胺还原以生成仲胺)会对活性和选择性产生显著影响,从而实现了等规聚乳酸的合成。
