This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Christopher A. Reed at the University of California at Riverside to develop a new class of weakly coordinating anions based on the icosahedral carborane. New carborane acids will be synthesized to open new areas of acid chemistry by: (a) protonating molecules previously considered too weakly basic to protonate such as Xe and Cr(CO)6; (b) protonating delicate molecules that decompose in acid such as P4, S8, and fullerenes; and, (c) allowing for the isolation of intermediates of acid catalyzed processes for detailed study on the preparative timescale. A super-methylating reagent consisting of a methyl cation and carborane anion will also be developed. The chemistry of a superoxidants involving triarylaminium carboranes will be explored. The synthetic inorganic chemistry emphasizes the isolation of pure materials and their characterization by single crystal X-ray structure determination. This project develops new super- acid, methyl and oxidant chemistry and will involve students from traditionally under-represented groups, particularly Hispanics, who are among the populations served by UC Riverside to attract them to frontline chemical research and careers in chemistry.

这个无机、生物无机和有机金属化学项目的奖项支持加州大学河滨分校的Christopher a . Reed教授开发一种基于二十面体碳硼烷的新型弱配位阴离子的研究。新的碳烷酸将被合成，通过(a)质子化以前被认为碱性太弱而不能质子化的分子，如Xe和Cr(CO)6，开辟酸化学的新领域；(b)质子化在酸中分解的精细分子，如P4、S8和富勒烯；(c)允许分离酸催化过程的中间体，以便对制备时间尺度进行详细研究。还将研制一种由甲基阳离子和碳硼烷阴离子组成的超甲基化试剂。探讨了含三芳胺碳硼烷的超氧化剂的化学性质。合成无机化学强调纯材料的分离和单晶x射线结构的测定。该项目开发了新的超酸性、甲基和氧化剂化学，并将吸引来自传统上代表性不足的群体的学生，特别是西班牙裔学生，他们是加州大学河滨分校服务的人群之一，以吸引他们从事化学前沿研究和职业。
