中文摘要: 受阻Lewis酸碱对化学由于开辟了一种新的小分子活化和催化模式,得到了广泛的关注。但目前对其的研究基本集中于大位阻的主族元素硼/膦体系。本研究拟合成以稀土金属作为Lewis酸,膦配体作为Lewis碱的分子内受阻Lewis酸碱对体系,并研究其与小分子的反应以及催化反应。设计侧链含膦基的三齿β-二亚胺配体稳定相应的稀土金属配合物。通过对这类化合物的成键模式和反应性能的研究既可以推动受阻Lewis酸碱对化学这一新兴领域的发展,同时也对传统稀土金属有机化学的发展有着重要的意义。

英文摘要: Frustrated Lewis pair (FLP) chemistry has recently received considerable attention as it offers a new strategy for small molecules activation and catalysis. However, most study about FLP were based on steric bulky main group boron/phosphine systems. Here, we propose to extend the concept of FLP to Lewis acidic rare-earth metals. We will prepare some neutral rare-earth metal complexes supported by pendant phosphine containing tridentate β-diketiminato ligands and explore their application in small molecules activation and catalysis. We believe that this project by using rare-earth metal Lewis acid will not only enlarge the scope of FLPs chemistry, but also reveal some unique reactivities and remarkable bonding features of rare-earth metal complexes.
