U.S.-Korea Cooperative Research on Free Radical Reactions ofNitro Compounds

9411164 Russell本奖项资助爱荷华州立大学化学系Glen a . Russell博士与韩国明知大学化学系Woonphil Baik博士进行为期30个月的硝基化合物自由基反应的合作研究项目。本研究将包括：(1)探索烯丙基硝基阴离子在光刺激下与2-卤-2-硝基丙烷之间缺乏反应性的原因；(2)将基本的SRN1机制扩展到涉及脂肪族硝基化合物电子转移反应的新型自由基链过程。受阻的苯氧基与拴系的硝酸钠阴离子实现环化反应的可能性也将被研究。提出的研究将试图扩展对某些自由基链取代反应机制的一般理解与适当的阴离子（亲核试剂）。合作者是该提案领域中备受尊敬的研究人员。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学工程财团（KOSEF）的支持。＊＊＊

9411164 Russell This award provides funds to permit Dr. Glen A. Russell, Department of Chemistry, Iowa State University, to pursue with Dr. Woonphil Baik, Department of Chemistry, Myong Ji University, Korea, for 30 months, a program of cooperative research on free radical reactions of nitro compounds. This research will involve (1) exploring the reason(s) underlying the lack of reactivity between allylic nitronate anions and 2-halo-2-nitro-propanes when photostimulated and (2) extensions of the basic SRN1 mechanisms to new types of free radical chain processes involving electron transfer reactions of aliphatic nitro compounds. The possibility of achieving cyclization reactions of hindered phenoxide radicals with a tethered nitronate anion also will be investigated. The proposed research will attempt to extend general understanding of the mechanism of certain free radical chain substitution reactions with appropriate anions (nucleophiles). The collaborators are highly respected researchers in the field of the proposal. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF). ***
