Metal-Ligand Multiple Bonds, Dehydrogenation Chemistry and Catalytic Transformations of Small Molecules Such as Methane, Ethane, Other Hydrocarbons, and N2

通过这一奖项，化学系化学合成计划资助宾夕法尼亚大学的Daniel J.Mindiola教授和同事探索第4和第5族过渡金属(主要是低成本贱金属)在开发试剂方面的作用，这些试剂可以激活天然气和页岩气中存在的丰富碳氢资源，并将其转化为烯烃和胺等附加值产品。这项研究将集中于使用毒性较低和富含稀土的过渡金属来开发新的催化循环，以激活和使用这些挥发性碳氢化合物进行C-C和C-N键形成反应。Mindiola集团已经开发出能够在室温下使用钛试剂将乙烷和丙烷(存在于天然气和页岩气中)等烷烃转化为各自的烯烃、乙烯和丙烯的系统。除了积极参与未被充分代表的组织，Mindiola教授和他的团队还准备了有机金属试剂合成过程中关键环节的短视频剪辑，以努力开发更易于使用的方法来教授有机金属合成。该项目旨在激活甲烷和C2-C8直链碳氢化合物并将其转化为烯烃，涉及制备具有金属-碳多键的反应性络合物，特别是与由坚固的钳形或芳氧配体支撑的金属离子，如钛、钒和Nb。用不同的卡宾或氮氢受体来源测试这些反应部分，以使这些转化成为循环或催化的。挥发性烷烃的低温转移脱氢，特别是那些不适合作为液体燃料的烷烃的低温转移脱氢正在被探索。PI和他的团队广泛传播关于页岩气的化学用途以及费托反应和蒸汽裂解反应的信息。

With this award, the Chemical Synthesis program of the Chemistry Division is funding Professor Daniel J. Mindiola and co-workers from the University of Pennsylvania, to explore the role of group 4 and 5 transition metals, mainly base metals of low cost, to develop reagents that can activate and transform abundant hydrocarbon resources, present in natural gas and shale gas, into value-added products such as olefins and amines. The research will focus on the use of less toxic and earth abundant transition metals for the development of new catalytic cycles that can activate and use these volatile hydrocarbons for C-C and C-N bond forming reactions. The Mindiola group has developed systems that are capable of transforming alkanes such as ethane and propane (present in natural gas and shale gas) into their respective olefins ethylene and propene at room temperature using titanium reagents. In addition to being actively involved with underrepresented organizations, Professor Mindiola and his group prepare short video clips of key segments during the synthesis of organometallic reagents in an effort to develop more user-friendly approaches to the teaching of organometallic synthesis.This project aims to activate and transform methane and C2-C8 linear hydrocarbons to olefins and involves the preparation of reactive complexes possessing metal-carbon multiple bonds, specifically with metal ions such as Ti, V, and Nb supported by robust pincer or aryloxide ligands. These reactive moieties are tested with various carbine or nitrene hydrogen acceptors sources to render these transformations cyclic or catalytic. The low-temperature transfer dehydrogenation of volatile alkanes, especially the ones which are not useful as liquid fuels, is being explored. The PI and his group disseminate information broadly about the chemical uses of shale gas, as well as Fischer-Tropsch and steam-cracking reactions.
