In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Peter T. Wolczanski of the Department of Chemistry and Chemical Biology at Cornell University will explore the utilization of first row transition metals in new carbon-carbon bond forming reactions, selective dinitrogen binding reactions, the oxidative functionalization of hydrocarbons, and metal clusters as potential water reduction catalysts. Radical reactions are one means to oxidize hydrocarbons, but the lack of selectivity in these transformations limits their utility. The research proposed suggests a way of controlling radical processes that will permit selective oxidations to be performed. Furthermore, dihydrogen (H2) that is not produced from hydrocarbons (its predominant source) is a promising alternative fuel, and this research explores different approaches to water reduction as a means to produce H2.In terms of broader impacts, the proposed work could lead to new C-C bond forming processes that can be applied to the synthesis of commodity or fine (e.g., drugs) chemicals. Hydrocarbon oxidation and water splitting are critical synthesis and energy problems of the 21st century. The direct transformation of hydrocarbons to value-added products has the potential for enormous energy and cost savings. Graduate and undergraduate students will be trained in various spectroscopies, X-ray crystallography, kinetics and mechanistic evaluations, molecular orbital calculations as well as in handling air sensitive compounds. Dissemination of this research through presentations at meetings, and via the promotion of science at the 5th-grade level and to 8th grade girls, is included. The production of independent, versatile PhDs capable of adapting to a challenging and fluctuating postdoctoral, academic or industrial market is a concurrent human resource objective.

本研究由化学系化学合成项目资助，由Peter T.康奈尔大学化学与化学生物学系的Wolczanski将探索第一行过渡金属在新的碳-碳键形成反应，选择性二氮结合反应，碳氢化合物的氧化功能化以及金属簇作为潜在的水还原催化剂中的应用。自由基反应是氧化烃类的一种方法，但在这些转化中缺乏选择性限制了它们的应用。这项研究提出了一种控制自由基过程的方法，这将允许进行选择性氧化。此外，不是由碳氢化合物（其主要来源）产生的二氢（H2）是一种有前途的替代燃料，并且本研究探索了减少水作为产生H2的手段的不同方法。就更广泛的影响而言，所提出的工作可能导致新的C-C键形成过程，其可应用于商品或精细的合成（例如，药物）化学品。 烃类氧化和水裂解是21世纪的关键合成和能源问题。将碳氢化合物直接转化为增值产品具有节省大量能源和成本的潜力。研究生和本科生将接受各种光谱学，X射线晶体学，动力学和机械评估，分子轨道计算以及处理空气敏感化合物的培训。 包括通过在会议上的演讲以及通过在五年级和八年级女生中推广科学来传播这项研究。能够适应具有挑战性和波动的博士后，学术或工业市场的独立，多功能博士的生产是一个并行的人力资源目标。
