In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Christopher Reed of the Department of Chemistry at the University of California, Riverside will explore the extremes of cation chemistry by utilizing the most stable, least basic, least coordinating anion - the perfluorinated carborane anion. The conjugate acid of this anion may be the world's strongest acid. It should be a strong enough acid to add H+ to some of the most weakly basic molecules, ones that have not been protonated before (e.g. Xe). The acid will also be explored as a novel catalyst for acid-catalyzed reactions such the room temperature cracking of hydrocarbons and the decomposition of halocarbons and freons. There are potential uses in the remediation of halocarbon chemical waste, converting it into useful hydrocarbons fuels.The broader impacts of this research include the possibility that new knowledge about cations, acidity and inert anions will impact commercially important areas such as petroleum reforming, polymerization catalysis, battery technology and fuel cell technology. The grant is primarily a vehicle for student training in research. UC Riverside has a high population of students from traditionally under-represented groups (e.g. Hispanics) so this project provides excellent opportunities for involving them in frontline chemical research and attracting them to careers in science.

在这个由化学系化学合成项目资助的项目中，加州大学滨江化学系的克里斯托弗·里德教授将利用最稳定、碱性最低、配位最少的阴离子-全氟碳硼烷阴离子来探索阳离子化学的极端。 这种阴离子的共轭酸可能是世界上最强的酸。它应该是一种足够强的酸，可以将H+加到一些最弱碱性的分子上，这些分子以前没有被质子化过（例如H2O）。该酸还将被探索作为酸催化反应的新型催化剂，如烃类的室温裂解和卤代烃和氟里昂的分解。卤化碳化学废物的补救有潜在的用途，将其转化为有用的碳氢化合物燃料，这项研究的更广泛的影响包括关于阳离子，酸度和惰性阴离子的新知识将影响石油重整，聚合催化，电池技术和燃料电池技术等重要的商业领域。该补助金主要是用于对学生进行研究培训的工具。加州大学滨江有一个传统上代表性不足的群体（如西班牙裔）的学生人口众多，所以这个项目提供了极好的机会，让他们参与一线化学研究，并吸引他们在科学事业。
