CAREER: Metal-Metal Multiply Bonded Redox-active Scaffolds for Transition Metals

无机化学、生物无机化学和金属有机化学项目的这一职业奖支持威斯康星大学麦迪逊分校的约翰·F·贝里教授研究金属-金属多键基团与其他接近的金属原子的相互作用。将合成一类新的配位化合物，其特征是过渡金属和富含电子的金属-金属多键基团之间的异金属相互作用。将用多种物理方法探索金属-金属多键基团的电子密度贡献，目的是发现由这些化合物促进的多电子氧化还原反应的新途径。将收集化学信息，并以基于计算机的动手学习模块的形式组合成教学上有用的基于数据的练习，作为研究生和本科生课程的补充。这些数据还将以在线互动网站或维基的形式呈现给整个化学界。异金属相互作用在多电子生物过程中非常重要，这些过程对生命至关重要，从能量转换的角度来看也具有工业重要性。通过使用分子氧或过氧化氢来发挥作用的新的氧化转化的发现与改善工业规模氧化化学的环境影响有关。

This CAREER award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professor John F. Berry at the University of Wisconsin - Madison to study the interaction of metal-metal multiply bonded groups with other metal atoms held in close proximity. A new class of coordination compounds will be synthesized that feature heterometallic interactions between a transition metal and an electron-rich metal-metal multiply bonded group. Donation of electron density from the metal-metal multiply bonded group will be probed using multiple physical methods with the aim of discovering new avenues for multi-electron redox reactivity promoted by these compounds. Chemical information will be collected and assembled into pedagogically useful data-based exercises in the form of computer-based hands-on learning modules as supplements to graduate and undergraduate coursework. These data will also be presented to the entirety of the chemical community in the form of an online interactive website or wiki.Heterometallic interactions are important in multi-electron biological processes that are essential to life and are also of industrial importance from the standpoint of energy conversion. The discovery of new oxidative transformations that function via the use of molecular oxygen or hydrogen peroxide is relevant to improving the environmental impact of industrial-scale oxidative chemistry.
