Metallacarboranes: Syntheses, Structures and Reactivities

化学部的无机化学、生物无机化学和金属有机化学项目支持北伊利诺伊大学化学和生物化学系Narayan S.Hosmane博士研究主族、过渡元素和稀土元素的金属碳烷的合成、结构和反应活性。该项目将开发专门针对构建主族金属、过渡金属和稀土金属的混合开二烯基金属碳硼烷夹心配合物；3-5族过渡金属、稀土元素和一些中间过渡元素金属的碳硼基-硫醇桥联茂金属衍生物；在结构上基于Hoveyda-GRubbs催化剂的碳硼烷基钌催化体系；以及碳硼烷和金属碳硼烷附加的单壁碳纳米管和富勒烯的合成。这些材料的催化性能和进一步的反应活性将被评估。这项研究的目标是生产一些新的和新颖的化合物，其中包含碳和/或硼结合各种金属的笼子。这些物种可能在硼中子俘获疗法和均相催化等应用中有用。参与这个项目的学生，包括毕业生和本科生，将学习广泛的合成技能。

The Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division supports Dr. Narayan S. Hosmane, Department of Chemistry and Biochemistry Northern Illinois University, for research into the synthesis, structure, and reactivity of metallacarboranes of main-group, transition, and lanthanide elements. The project will develop syntheses specifically aimed at constructing mixed open- pentadienylmetallacarborane sandwich complexes of main group, transition and lanthanide metals; carboranyl-chalcogenol-bridged metallocene derivatives of groups 3-5 transition metals, lanthanides, and some metals of the mid-transition elements; carborane-based ruthenium catalytic systems structurally based on the Hoveyda-Grubbs catalyst; and carborane- and metallacarborane-appended single-wall carbon nanotubes and fullerenes. The catalytic properties and further reactivity of these materials will be evaluated.The goal of this research is to produce a number of new and novel compounds containing cages of carbon and/or boron combined a wide range of metals. These species might be useful in applications such as boron neutron capture therapy and in homogeneous catalysis. The students involved in this project, both graduates and undergraduates, will learn a breadth of synthetic skills.
