Synthesis and Spectroscopy of Reduced Bis(imino)pyridine Iron Catalysts

该奖项在无机，生物无机和有机化学计划支持研究保罗Chirik教授在康奈尔大学开发新的铁催化剂的选择性有机转化。该方法旨在阐明双（亚氨基）吡啶铁衍生物的电子结构，并将这些知识应用于合成新的，更环保的化合物，这些化合物是形成C-H，C-C和C-Si键的活性催化剂。 该研究将探索新结构类型的电子结构和催化活性，如铁酰亚胺，氮化物，重氮烷络合物和亚烷基，以开发催化系统，用更便宜，更环保的铁化合物取代有毒和昂贵的贵金属。这项研究将与位于德国穆尔海姆的马克斯普朗克生物无机化学研究所的Karl Wieghardt教授合作进行。 参与该项目的学生和博士后将在康奈尔大学和马克斯普朗克研究所的实验室中度过一段时间，并接触到合成，光谱学和计算方法的补充活动。一个重要的重点是开发和利用旨在促进数据交换和管理的网络基础设施。这些活动将作为社区外展的基础，包括为经济上处于不利地位的学生提供的方案和为代表性不足的少数民族提供的新的科学机会。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Prof. Paul Chirik at Cornell University to develop new iron catalysts for selective organic transformations. The approach seeks to elucidate the electronic structure of bis(imino)pyridine iron derivatives and apply this knowledge to the synthesis of new, more environmentally responsible compounds that are active catalysts for the formation of C-H, C-C and C-Si bonds. The research will explore the electronic structure and catalytic activity of new structural types such as iron imides, nitrides, diazoalkane complexes and alkylidenes in order to develop catalytic systems that would replace toxic and expensive precious metals with cheaper, more environmentally benign iron compounds. This research will be carried out in collaboration with Prof. Karl Wieghardt at the Max Plank Institute for Bioinorganic Chemistry in Mulheim, Germany. Students and postdocs involved in the project will spend time in laboratories at both Cornell and the Max Plank Institute and be exposed to complementary activities in synthesis, spectroscopy and computational methods. An important focus is the development and utilization of a cyber infrastructure designed to facilitate data exchange and management. These activities will serve as the foundation for community outreach including programs for economically disadvantaged students and new scientific opportunities for underrepresented minorities.
