coordination modes of aluminum complexes bearing amido-pyridinate and amido-benzene ligands. Utilizing pendant donating groups to switch the coordination behaviours of aluminum complexes and their catalytic activities. Noticeably, these Al complexes containing the methoxy group markedly showed reactivities in ring-opening polymerization of ε-caprolactone. Among them, complex 3 with the methoxy group coordinated
这项工作描述了带有氨基吡啶和氨基苯配体的铝配合物的各种配位模式。利用悬垂给体基团改变铝配合物的配位行为及其催化活性。值得注意的是,这些含有甲氧基的Al配合物在ε-己内酯的开环聚合中表现出显着的反应性。其中,与文献中其他相关的氨基铝配合物相比,金属中心配位甲氧基的配合物3在室温下表现出更高的性能和更低的催化剂负载量。
