The Reactions and Energetics of Organic Radical Ions and Doubly Charged Ions in Solution

这项有机和大分子化学的资助为犹他州立大学弗农·帕克博士的研究提供了支持。这项工作包括对有机阴离子自由基、阴离子、阳离子自由基和指示物的反应和反应性的系统研究。这些活性有机物质是各种有机反应的重要中间体，了解它们的行为具有重要的实际意义，特别是对电极过程和聚合反应。使用定量电化学方法，将研究许多类型的反应，包括(i)阳离子中间体与亲核试剂（中性和阴离子）的反应，（ii）阳离子自由基和甲基芳烃衍生物的质子转移反应，以及（iii）阴离子自由基和阴离子的质子化反应。将讨论的具体问题是(i)与相应的双带电离子相比，离子自由基的内在反应性和（ii）影响超酸性（碱性）离子自由基和双带电离子与碳之间质子转移速率的因素。这些将为反应中间体化学提供重要的基础新知识。

This grant in Organic and Macromolecular Chemistry provides support for the research of Dr. Vernon Parker, Utah State University. The work consists of a systematic study of the reactions and reactivity of organic anion radicals, dianions, cation radicals, and dications. Such reactive organic species are important intermediates in a wide variety of organic reactions and an understanding of their behavior has important practical signficance, particularly for electrode processes and polymerization reactions. Using quantitative electrochemical methods, a number of reaction types will be studied including (i) reactions of cationic intermediates with nucleophiles, both neutral and anionic, (ii) proton transfer reactions of cation radicals and dications derived from methylarenes, and (iii) protonation reactions of anion radicals and dianions. Specific issues which will be addressed are (i) the intrinsic reactivity of ion radicals as compared to the corresponding doubly charged ions and (ii) the factors contributing to the rates of proton transfer to and from carbon of super acidic (basic) ion radicals and doubly charged ions. These will provide fundamental new knowledge of importance to reactive intermediate chemistry.
