Syntheses and Reactivity of Ruthenium Complexes Containing B-Phenylethynyl or Phenyl Substituted Boratabenzene Ligands

Abstract

硼杂苯(Bb)(boratabenzene)是含6个电子的芳香性杂环,其配位行为与化学性质和环戊二烯基离子(Cp)类似,可作为Cp的等电子配体,又可以方便地通过改变硼上的取代基调节配体的电子性质和空间位阻,从而调控相应配合物的反应性质。本论文合成了一系列的硼杂苯钌配合物及其相关化合物,并对其进行了表征,同时对于部分产物的反应性质进行了研究。论文分为以下三个部分: 第一章为绪论,结合本论文核心内容简要介绍了硼杂苯、硼杂苯配合物以及半夹心型环戊二烯基钌配合物(η5-C5R5)RuXL2研究进展,同时阐述了本论文的设想与主要研究内容。 第二章为硼杂苯钌配合物(6-...Boratabenzenes are six-membered aromatic borataheterocycle bearing six π-electrons, which are isoelectronic and isostructural with the ubiquitous cyclopentadienyl ligands. Their coordination properties are similar to that of Cp. In addition, it is easier to modulate their electronic contributions by the choice of the exocyclic substituent on boron.In this thesis, a series of half-sandwich rutheniu...学位:理学硕士院系专业:化学化工学院_有机化学学号:2052009115144
