Dr. Francois P Gabbai, Chemistry Department, Texas A&M University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program to explore the synthesis of cationic boranes, their electrochemistry and their reduction into neutral radicals. More specifically, monofunctional and bifunctional cationic boranes featuring pyridinium, acridinium, ammonium, phosphonium and sulfonium moieties will be prepared. These compounds with be reduced to determine if the cationic character of the boranes serves to decrease their reduction potential and increase the stability of the resulting radicals. Unusual unusual bonding motifs including one-electron boron-boron sigma and pi bonds will be investigated both experimentally and theoretically. These studies should reveal how the cationic nature of the boranes influences their oxidative power. This research will advance the fundamental understanding of the bonding of the main group elements. The compounds produced in this study will be strong oxidants and applications in the oxidation of organic compounds are anticipated. Graduate students, undergraduate students and postdoctoral associates will receive excellent training and research experiences in forefront synthetic inorganic chemistry.

德克萨斯农工大学化学系的 Francois P Gabbai 博士在无机、生物无机和有机金属化学项目的支持下，探索阳离子硼烷的合成、电化学以及还原成中性自由基。更具体地，将制备具有吡啶鎓、吖啶鎓、铵、鏻和锍部分的单官能和双官能阳离子硼烷。将这些化合物还原以确定硼烷的阳离子特性是否有助于降低其还原电位并增加所得自由基的稳定性。不寻常的键合基序包括单电子硼-硼西格玛和π键将在实验和理论上进行研究。这些研究应该揭示硼烷的阳离子性质如何影响其氧化能力。这项研究将增进对主族元素键合的基本理解。本研究中产生的化合物将是强氧化剂，预计可应用于有机化合物的氧化。研究生、本科生和博士后将获得前沿合成无机化学领域的优秀培训和研究经验。
