Transition metal complexes with ambiphilic and borabenzene ligands and their reactivity with small molecules

路易斯酸在过渡金属催化中发挥了重要作用，但与路易斯碱分子相比，含硼和含铝物质的配位化学研究仍然不足。在过去的十年里，几个研究小组一直在研究路易斯酸和过渡金属之间的相互作用，利用路易斯碱的螯合作用，形成一种正式的称为亲两性配体的物质。我们的研究小组对这些两亲分子与过渡金属的相互作用很感兴趣。在接下来的五年里，我们的研究计划将研究两个不同的骨干。首先，我们将继续研究一般形态为L-E-Z的配体（L =路易斯碱，E =单原子间隔剂，Z = B-或Al-路易斯酸）。我们还将研究在硼苯框架的不同位置整合官能团，以产生与过渡金属以一种新颖的方式相互作用的物种，而不涉及芳香环的pi系统。

Lewis acids have played an important role in catalysis using transition metals, but the coordination chemistry of boron and aluminum containing species is still understudied compared to that of Lewis basic molecules. Over the past decade, several research groups have look at stabilizing interactions between Lewis acids and transition metals using chelation with a Lewis base, forming what are formally called ambiphilic ligands. Our group is interested in the interaction of these ambiphilic molecules with transition metals. Two different backbones will be studied in the next five years of our research program. First, we will continue our investigation of ligands having the general morphology L-E-Z (L = Lewis base, E = a one-atom spacer, Z = B- or Al- Lewis acid). We will also look at integrating functional groups in various positions of a borabenzene framework in order to generate species that will interact with transition metals in a novel fashion not involving the pi system of the aromatic ring.
