Full-Collision and Half-Collision Studies of the Dynamics of Model C-H Bond Activation Processes

犹他大学的William Breckenridge教授在实验物理化学项目的支持下，对含有金属中心的气态团簇中C-H键的激活进行了实验。该提案旨在发现C-H键断裂发生在气相团簇中的机制，模拟两种情况：金属电子与C-H键的侧向相互作用，如在有机金属化合物中发生的那样，以及金属氧化物表面上的C-H键激活。这些团簇将使用各种激光探针，如激光诱导荧光和多光子电离光谱进行研究。简单金属-碳氢化合物体系的结构和动力学问题通过与现实世界的催化问题的比较，在这个建议中变得非常相关。碳氢键的断裂在烃类裂解、催化、天然气合成、加氢和有机合成等许多重要工艺过程中都引起了人们的极大兴趣。

Professor William Breckenridge of the University of Utah is supported by the Experimental Physical Chemistry program to perform experiments on the activation of C-H bonds in gaseous clusters containing metal centers. This proposal seeks to discover mechanisms by which C-H bond breaking occurs in gas phase clusters mimicking two situations: side-on interactions of metal electrons with C-H bonds as would occur in organometallic compounds, and C-H bond activation on the surfaces of metal oxides. The clusters will be studied using various laser probes such as laser-induced fluorescence, and multiphoton ionization spectroscopy. The problem of structure and dynamics in simple metal-hydrocarbon systems is made quite relevant in this proposal by the comparison to real world problems in catalysis. The breaking of C-H bonds is of great interest in a variety of important technological processes such as hydrocarbon cracking, catalysis, synthesis of chemicals from natural gas, hydrogenation and organic synthesis.
