Abstract

We report an aniline ligand (1) with two bis(pyrazolyl)alkane arms, and its cationic, dizinc complexes. XRD, NMR, and modelling of the dizinc complexes resulted in an unprecedented, dynamic μ-anilide core. Compared with published μ-phenolate analogues, our μ-anilide complexes show higher activity and divergent counterion trends in ring-opening polymerization of rac-lactide.

用于二锌催化开环聚合的苯胺桥接双（吡唑）烷配体

我们报告了一种具有两个双（吡唑）烷臂的苯胺配体（1）及其阳离子二锌配合物。通过 XRD、NMR 和对二锌配合物的建模，我们发现了一种前所未有的动态  苯胺核心。与已发表的 -苯酚类似物相比，我们的 -anilide 复合物在 rac-lactide 的开环聚合反应中显示出更高的活性和不同的反离子趋势。
