Fe-mediated C-O cleavage and C-C bond forming reactions from CO2 and CO substrates

该奖项由无机、生物无机和有机金属化学项目颁发，支持麻省理工学院乔纳斯·彼得斯教授研究（膦酸盐）铁(I)化合物的工作，这些化合物由于其相对较低的配位数和几何结构而在结构上不寻常。这些配合物具有铁氮多键。这些配合物被发现介导C-O裂解途径，影响部分或完全CO挤压或还原性C-C偶联产生草酸盐。单金属和双金属铁（氧）的合成也将探讨，特别是在二氢活化方面。最后，激活二氧化碳和释放铁羰基产物的能力为利用二氧化碳作为C-C偶联反应的合成物打开了大门，这种反应利用CO作为碳或碳炔前体。研究了铁（碳炔）和（碳炔）的合成及其与氢的反应性。除了二氧化碳的还原性降解可能对温室气体的减少和碳管理新方法的发展产生重要影响之外，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量转换问题变得敏感。

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.
