Metallocene Mediated, Electrocatalytic Oxygen Atom Transfer Reactions

该奖项是作为Chad Mirkin博士化学博士后研究奖学金的启动资助增量，以支持他在西北大学的研究。研究早期过渡金属茂金属介导的电催化氧原子转移反应。该研究的目标是通过电化学、光化学和化学方法来发展电催化氧化反应，产生与聚合物载体结合的高活性有机金属，作为氧原子转移催化剂。氧原子源是二氧化碳和水，典型的底物是烯烃。预计产物为环氧化物和酮类。催化剂种类将在支撑表面上被隔离，并进行光谱表征。催化循环中的各个步骤将通过红外和ESR光谱来确定。催化氧原子转移反应具有重要的商业意义。烯烃的环氧化反应目前正在大规模进行。新的、更高效的催化剂可能会对商业技术以及对基本氧化机制的理解产生重大影响。

This award is made as the starter grant increment of Dr. Chad Mirkin's Postdoctoral Research Fellowship in Chemistry award in support of his research at Northwestern University. Early transition metal metallocene-mediated, electrocatalytic oxygen atom transfer reactions will be studied. The goal of the research will be to develop electrocatalytic oxidation reactions by electrochemically, photochemically and chemically generating highly reactive organometallic species bound to a polymer support for use as oxygen atom transfer catalysts. Oxygen atom sources will be carbon dioxide and water and typical substrates will be olefins. Expected products will be epoxides and ketones. Catalyst species will be site-isolated on supported surfaces and spectroscopically characterized. Individual steps in the catalytic cycle will be defined by infrared and ESR spectroscopy. %%% Catalytic oxygen atom transfer reactions are of great commercial importance. The epoxidation of olefins is currently carried out on a large scale. New, more efficient catalysts could have a major impact both on commercial technology as well as on understanding fundamental oxidation mechanisms.
