mononuclear aluminum dimethyl complexes bearing bidentate N-[2-(1-piperidinyl)benzyl]anilino or N-(2-morpholinobenzyl)anilino ligands were synthesized via reactions of the corresponding proligands with trimethylaluminum upon heating, while at ambient temperature two trimethylaluminum adducts with neutral N-[2-(1-piperidinyl)benzyl]aniline proligands were obtained. These complexes were well characterized
加热条件下,通过相应配位体与三甲基铝的反应,合成了一系列带有二齿N- [2-(1-哌啶基)苄基]苯胺基或N-(2-吗啉代苄基)苯胺基配体的单核二甲基铝配合物。得到具有中性N- [2-(1-哌啶基)苄基]苯胺配体的三甲基铝加合物。这些配合物已通过NMR光谱,元素分析以及EI-HRMS进行了很好的表征。典型的三甲基铝加合物2b和二甲基铝配合物3b的分子结构X射线衍射研究进一步证实了这一点。所有的二甲基铝配合物都可以以良好控制的方式有效地引发外消旋丙交酯的开环聚合(ROP),从而提供分子量分布较窄的PLA(PDI = 1.06-1.18)。通过1 H NMR和ESI-TOF质谱表征,将获得的聚合物样品用双齿辅助配体系统地封端。此外,在配体的苯胺基部分的邻位处引入取代基导致相应的铝配合物以及与间位的配合物的催化活性明显降低。-氯取代的苯胺基单元显示出更高的活性,这可能是由于苯胺基基团诱导的金属中心的亲电子性增强。
