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，加州大学河滨分校化学系的Christopher Reed教授将利用最稳定、碱性最低、配位最少的阴离子——阴离子来探索阳离子化学的极限。全氟化碳硼烷阴离子。 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+ 添加到一些最弱的碱性分子中，这些分子之前没有被质子化（例如 Xe）。该酸还将被探索作为酸催化反应的新型催化剂，例如碳氢化合物的室温裂化以及卤化碳和氟利昂的分解。在修复卤化碳化学废物方面有潜在用途，将其转化为有用的碳氢化合物燃料。这项研究的更广泛影响包括关于阳离子、酸度和惰性阴离子的新知识可能会影响石油重整、聚合催化等商业重要领域、电池技术和燃料电池技术。该补助金主要是学生研究培训的工具。加州大学河滨分校拥有大量来自传统上代表性不足的群体（例如西班牙裔）的学生，因此该项目为让他们参与前沿化学研究并吸引他们从事科学事业提供了极好的机会。
