Activation of Oxygen: Mechanistic Aspects of Electron Transfer and Atom Transfer

该奖项由无机、生物无机和有机物化学项目授予爱荷华州州立大学的Andreja Bakac教授，旨在支持开发生成含水铬（V）离子的新方法的研究，检查溶液中氧原子的反应性，并对铬（II）络合物和分子氧生成的中间体的形成和反应性进行研究。 在一般意义上，所有这些主题涉及氧活化和机械氧化化学的各个方面。 这项工作预计将产生关键的动力学数据和深入了解反应机制。 因此，拟议的研究的智力价值在于通过热和光化学手段对氧活化的基本理解的预期贡献。 这一建议的更广泛影响包括本科生、研究生和博士后研究员的教育和培训。此外，对氧活化的机理研究为在更环境友好的反应中利用分子氧的催化过程的发展提供了基础。 由于分子氧、金属络合物和有机物之间的恒定和复杂的相互作用，这种化学在生物系统中也起着重要作用。

This award by the Inorganic, Bioinorganic and Organometallic Chemistry Program to Professor Andreja Bakac of Iowa State University is to support research on the development of new methods for generating aqueous chromium(V) ions, to examine the reactivity of oxygen atoms in solution, and to carry out studies on the formation and reactivity of intermediates generated from chromium(II) complexes and molecular oxygen. In a general sense, all of these topics deal with various aspects of oxygen activation and mechanistic oxidative chemistry. The work is expected to produce crucial kinetic data and insight into the reaction mechanisms. The intellectual merit of the proposed research thus lies in the expected contribution to the fundamental understanding of oxygen activation by thermal and photochemical means. The broader impacts of this proposal include the education and training of undergraduate and graduate students and postdoctoral associates. Additionally, mechanistic studies on oxygen activation provide a basis for the development of catalytic processes utilizing molecular oxygen in more environmentally benign reactions. Such chemistry also plays a major role in biological systems owing to the constant and complex interactions between molecular oxygen, metal complexes, and organic matter.
