Main Group Metallacarboranes and Metallaboranes: Chemistry in New Directions

无机化学、生物无机化学和金属有机化学项目的这一奖项支持北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。我们将研究“碳分离”四碳-N-十二硼烷和稠合的[B22H22]阴离子和[C2B22H22]笼与S和P-嵌段元素的反应性。特别是，Cs、Sr、Ba、Ga和In与这些笼子反应生成的化合物将被合成，并进行结构和理论研究。将确定其中一些笼状化合物从水溶液中提取Cs离子的能力，以及它们作为合成子的多功能性程度，以生成各种包含主基、d-和f-嵌段元素的全夹心和半夹心配合物。这项研究的目标是生产一些新的和新颖的化合物，这些化合物包含碳和/或硼与重金属或半金属(如镓和铟)结合的笼子。这些材料可以帮助从放射性废物中回收铯，并作为半导体、陶瓷和催化剂形成的前体，从而在修复中使用。参与这个项目的学生，包括研究生和本科生，将学习广泛的合成和计算技能，并获得工作在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.
