Synthesis and Studies of Selected Metal Carbonyl Clusters and Their Boron Containing Derivatives

该奖项授予俄亥俄州立大学化学系的Sheldon G.Shore博士，以表彰其合成新的过渡金属羰基簇合物。用作起始材料的簇中的金属数量通常为六个，金属为Ru或Os。已知团簇中CO的损失产生了新的物种，可用于合成含有七个金属原子的混合金属团簇。将尝试将硼封装到由此形成的混合金属团簇中。更多的目标分子是由稀土阳离子与Ru、Fe和铁-Ru碳化物反应产生的。在该项目的第二部分，将研究氧化镁表面团簇的行为，特别是关于质子转移、热降解和与氢的反应。这个项目涉及开发金属和双金属羰基化合物的新合成方法。所制备的一些物种将用于生产含有缺电子的硼烷或碳硼烷的金属簇合物。其他的将与固体氧化镁反应，以模拟表面反应。这项工作对了解有机金属化合物的成键和反应活性以及多相催化都有应用价值。

This award in the Inorganic, Bioinorganic, and Organometallic Program is to Dr. Sheldon G. Shore of the Department of Chemistry, Ohio State University, for synthesis of new transition metal carbonyl cluster compounds. The number of metals in the cluster used as the starting material is typically six, and metals are Ru or Os. Loss of CO from known clusters results in new species which can be utilized in the synthesis of mixed metal clusters containing seven metal atoms. Attempts will be made to encapsulate boron into the mixed-metal clusters thus formed. Additional target molecules result from reaction of lanthanide cations with ruthenium, iron, and iron-ruthenium carbonylates. In a second part of the project, the behavior of clusters on magnesia surfaces will be investigated, especially with respect to proton transfer, thermal degradation, and reaction with hydrogen. %%% This project involves the development of new synthetic methods for metallic and bimetallic carbonyls. Some of the species prepared will be used to produce metal cluster compounds containing electron-deficient boranes or carboranes. Others will be reacted with solid magnesia to model surface reactions. This work has application both to understanding bonding and reactivity of organometallic compounds and to heterogeneous catalysis.
