项目摘要
My group pursues research in the chemistry of metal ions and is specifically interested in oxidation processes. Industry has a great need for energetically viable and environmentally friendly reactions that convert hydrocarbons, the constituents of oil and natural gas, into useful chemicals. Yet, the direct oxidative transformation of hydrocarbons remains tremendously difficult to achieve in mild conditions. Nature has optimised many such reactions through the use of metal-containing enzymes which operate in environmentally friendly conditions; it is therefore a great source of inspiration for this chemistry. The research goals of my group are thus two-fold: (1) understand the origin of the efficiency of the enzymes, and (2) prepare catalysts that can perform similar reactions. Our initial approach is to model the enzymatic active sites with small metal-containing molecules (called metal complexes) and study their reactivity behaviour. Comparison of the models and the enzymes will inform us on the factors necessary to achieve a strong reactivity. Next, we will implement these factors in metal complexes to perform efficient catalysis. In the short term, this research will provide a better understanding of (1) the toolkit used by nature and (2) how to use oxygen as a clean oxidant that generates no waste. In the long term, our discoveries will guide the design of oxidative hydrocarbon transformations that minimise the number of steps and waste by-products. Because the metal complexes are designed to be highly reactive, they require to be prepared in the absence of oxygen and water. The equipment requested in the present application serves this purpose: the glovebox worstation will ensure an inert atmosphere of high quality while the solvent purification system will dry and remove oxygen from the solvents used to prepare the reactive metal complexes.
我的小组从事金属离子化学的研究,特别对氧化过程感兴趣。工业非常需要能量上可行的和环境友好的反应,将碳氢化合物,石油和天然气的成分,转化为有用的化学品。然而,烃的直接氧化转化在温和条件下仍然非常难以实现。大自然已经通过使用在环境友好条件下操作的含金属的酶优化了许多这样的反应;因此,它是这种化学的灵感来源。因此,我的团队的研究目标有两个方面:(1)了解酶效率的起源,(2)制备可以进行类似反应的催化剂。我们最初的方法是用含金属的小分子(称为金属络合物)模拟酶的活性位点,并研究它们的反应行为。模型和酶的比较将告知我们实现强反应性所需的因素。接下来,我们将在金属络合物中实现这些因素,以进行有效的催化。在短期内,这项研究将提供更好的理解(1)自然界使用的工具包和(2)如何使用氧气作为一种清洁的氧化剂,不产生废物。从长远来看,我们的发现将指导氧化碳氢化合物转化的设计,最大限度地减少步骤和废弃副产品的数量。由于金属络合物被设计成具有高反应性,因此它们需要在不存在氧和水的情况下制备。本申请中要求的设备用于此目的:手套箱工作站将确保高质量的惰性气氛,而溶剂纯化系统将干燥并从用于制备活性金属络合物的溶剂中除去氧气。
