讲座摘要/Abstract:

过渡金属催化氧化还原反应的活性与金属的价态密切相关，而实验上最难解决的一个问题就是确认反应过程中金属的价态及其变化模式。因此，针对氧化还原催化金属价态的研究是该领域的研究难点和热点之一。我们聚焦于含过渡金属的天然酶和仿生物功能配合物催化氧化还原反应的化学本质，通过建立接近真实条件的模型并利用量子化学团簇和QM/MM方法准确描述金属价态在氧化还原催化过程中的作用，借鉴金属酶催化机制理解仿生配合物催化机制。

The oxidation state of the metals is crucial for the catalytic activity of redox reactions mediated by transition metal complexes, and one of the most challenging questions in experiments is to identify the metal oxidation states and their change mode during the reaction. The investigation of metal oxidation states and the corresponding reaction pathways is thus a challenging and hot topic in redox catalysis. Here, we focused on the chemistry of redox reactions catalyzed by metalloenzymes and bio-inspired synthetic complexes. Based on models constructed to represent the experimental conditions, the quantum chemical cluster and the combined quantum mechanics/molecular mechanics approaches were applied to study the role of metal oxidations states in the redox catalytic processes, and the enzymatic mechanism was used to inspire further understanding on the catalytic mechanism by synthetic complexes. Several examples are presented.
