Quantifying the Interplay of Structure and Reactivity in Ring Closing and Cross Metathesis

拟议的计划将使用一些综合访问系统，以提高我们的定量了解的烯烃环闭合methathesis（RCM）和交叉复分解（CM）反应的有机反应机理。我们希望确定有效摩尔浓度（EM）作为环尺寸n和取代模式的函数，以测量绝对环化和低聚速率，并使用计算方法来理解这些数据。该计划将开发物理有机化学（实验动力学，计算方法）的专业知识和工具，同时研究具有相当重要的基本重要性和当前相关性的反应。我们建议协同使用计算和实验动力学技术来完善和/或挑战有关RCM反应机制方面的基本和一般想法，将反应纳入POC的专业领域。我们还希望发展互补的见解交叉复分解（CM）反应，见解，如果我们要充分了解环化效率的问题所需的。该计划的成功交付将大大推进研究知识，并为英国在烯烃复分解化学的重要和热门领域做出相当大的贡献。

The proposed programme will use a number of synthetically accessible systems to improve our quantitative understanding of the organic reaction mechanism of the alkene ring closing methathesis (RCM) and cross metathesis (CM) reactions. We wish to determine effective molarities (EMs) as a function of ring size n and substitution patterns, to measure absolute cyclisation and oligomerisation rates, and to use computational methods to understand these data. The programme will develop expertise and tools in physical organic chemistry (experimental kinetics, computational methods) while investigating a reaction of considerable fundamental importance and acute current relevance. We propose to use computational and experimental kinetic techniques synergistically to refine and/or challenge fundamental and general ideas about aspects of the mechanism of RCM reactions, bringing the reaction within the domain of expertise of POC. We also wish to develop complementary insight concerning cross metathesis (CM) reactions, insights which are required if we are to understand the issues surrounding cyclisation efficiency fully. The successful delivery of this programme will advance research knowledge significantly and make a considerable contribution to UK standing in the important and topical field of alkene metathesis chemistry.
