Main Group Metallacarboranes and Metallaboranes: Chemistry in New Directions

无机，生物无机和有机化学计划的这一奖项支持北方伊利诺伊大学化学和生物化学系的Narayan Hosmane教授对主族金属碳硼烷和金属硼烷化学的研究。将研究“碳分离”的四碳-巢-十二硼烷和稠合的[B22 H22]阴离子和[C2 B22 H22]笼与s-和p-区元素的反应性。特别地，将合成由Cs、Sr、Ba、Ga和In与这些笼反应产生的化合物，并进行结构和理论研究。将确定这些笼状化合物中的一些从水溶液中萃取Cs离子的能力，以及它们作为用于生产各种含主基的全夹心和半夹心配合物的多功能性的程度，本研究的目标是生产一些新的和新颖的化合物，其含有与重金属或半金属结合的碳和/或硼的笼。金属如镓和铟。这些材料可用于补救，帮助从放射性废物中回收铯，并作为形成半导体、陶瓷和催化剂的前体。参与该项目的学生，无论是研究生还是本科生，都将学习广泛的合成和计算技能，并获得环境和工业应用方面的经验。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research on the chemistry of main group metallacarboranes and metallaboranes by Professor Narayan Hosmane of the Department of Chemistry and Biochemistry at Northern Illinois University. The reactivity of the "carbons apart" tetracarba-nido-dodecaborane and fused [B22H22] anionic and [C2B22H22] cages with s-and p-block elements will be investigated. In particular, compounds resulting from reaction of Cs, Sr, Ba, Ga and In with these cages will be synthesized, and subjected to structural and theoretical studies. The ability of some of these cage compounds to extract Cs ion from aqueous solution will be determined, as will the extent of their versatility as synthons for the production of a variety of full and half-sandwich complexes containing main group, d-and f-block elements.The goal of this research is to produce a number of new and novel compounds containing cages of carbon and/or boron combined with heavy metals or semi-metals such as gallium and indium. These materials may find use in remediation by helping to reclaim cesium from radiactive wastes and as precursors in the formation of semiconductors, ceramics and catalysts. The students involved in this project, both graduate and undergraduate, will learn a breadth of synthetic and calculational skills and gain experience in the environmental and industrial applications of the work.
