This award by the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports the work of Professor Jonas Peters at the Massachusetts Institute of Technology to investigate (phosphinoborate)iron(I) compounds that are structurally unusual by virtue of their relatively low coordination numbers and geometry. These complexes feature iron-nitrogen multiple bonds. These complexes have been found to mediate C-O cleavage pathways that effect partial or complete CO extrusion or reductive C-C coupling to produce oxalate. The synthesis of monometallic and bimetallic iron(oxo) species will also be explored particularly in terms of dihydrogen activation. Finally, the ability to activate carbon dioxide and release iron carbonyl products opens the door to using carbon dioxide as a synthon for C-C coupling reactions that exploit CO as a carbene or carbyne precursor. The synthesis and reactivities of iron(carbenes) and (carbynes) with hydrogen will also be investigated. In addition to the reductive degradation of carbon dioxide which may have important ramifications for the reduction of greenhouse gases and the development of new methods of carbon management, this research will encourage undergraduate and graduate students to become sensitive to energy conversion issues as they enter their chemical careers.

无机，生物无机和有机化学计划的这一奖项支持了马萨诸塞州理工学院的Jonas Peters教授的工作，以研究由于其相对较低的配位数和几何形状而在结构上不寻常的（膦基硼酸盐）铁（I）化合物。 这些配合物具有铁-氮多重键。 已发现这些复合物介导C-O裂解途径，从而影响部分或完全CO挤出或还原性C-C偶联以产生草酸盐。 还将特别在二氢活化方面探索Monoclonal和Monoclonal铁（氧代）物种的合成。 最后，活化二氧化碳并释放羰基铁产物的能力为使用二氧化碳作为C-C偶联反应的合成子打开了大门，该反应利用CO作为卡宾或碳炔前体。 铁（卡宾）和（卡宾）与氢的合成和反应性也将进行研究。除了二氧化碳的还原降解可能对减少温室气体和开发碳管理新方法产生重要影响外，这项研究还将鼓励本科生和研究生在进入化学职业生涯时对能源转换问题敏感。
