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.

无机化学、生物无机化学和金属有机化学项目的这一奖项支持康奈尔大学的Paul Chirik教授为选择性有机转化开发新的铁催化剂的研究。该方法旨在阐明双(亚氨基)吡啶铁衍生物的电子结构，并将这一知识应用于合成对环境更友好的新化合物，这些化合物是形成C-H、C-C和C-Si键的活性催化剂。这项研究将探索新结构类型的电子结构和催化活性，如亚铁、氮化物、重氮烷化合物和亚烷基化合物，以开发用更便宜、更环保的铁化合物取代有毒和昂贵的贵金属的催化系统。这项研究将与德国木尔海姆Max Plank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·普兰克研究所的实验室度过一段时间，并接触到合成、光谱和计算方法方面的补充活动。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宣传的基础，包括针对经济困难学生的方案和为代表不足的少数民族提供新的科学机会。
