  Novel Syntheses of Symmetric Alkyl-substituted β-Diketimines with Dimethylsulfate Assisted by Microwave

  摘要：

  我们提出了一种高效且新颖的对称${\beta}$-二酮亚胺的制备方法，该方法借助微波辅助进行。一系列N,N'-对称烷基取代的${\beta}$-二酮亚胺已通过二甲基硫酸与O-酰化反应合成。更高的重复性和产率、更低的成本以及由于无溶剂条件和更快的反应时间所带来的更高能量效率的绿色特性是这一新方法的主要优点。除了这些优点外，几乎所有类型的${\beta}$-二酮亚胺，包括较少报道的烷基取代${\beta}$-二酮亚胺，均已成功制备。预计这些化合物将在多个领域得到更广泛的应用。

  Al complexes bearing ketimine ligands was investigated. The catalytic results indicated complexes with more steric hindrance with an electron-withdrawing group on the ligands, or the fact that less chelating ligands demonstrated greater propagation activity. The opposite trend for these structural effects was observed on the measurement of induction periods. These features on ligands of aluminum complexes

  先前对使用结构相关的铝配合物作为前催化剂的ε-己内酯的开环聚合的研究表明，总转化时间的趋势不一致。我们建议应考虑将Al络合物转化为真正的催化物质Al醇盐的诱导期，因为总转化时间包括诱导期和聚合物扩散时间。在此，研究了一系列带有酮亚胺配体的Al配合物的聚合速率。催化结果表明与配体上的吸电子基团具有更大空间位阻的配合物，或螯合配体较少的事实表明具有更大的传播活性。在诱导期的测量中观察到这些结构效应的相反趋势。铝配合物配体上的这些特征有助于促进向烷氧基铝的转化过程。总体催化性能应同时考虑诱导期和传播​​时间。
