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

9411164 Russell该奖项提供资金，以允许爱荷华州立大学化学系Glen A.Russell博士与韩国明基大学化学系Woonphil Baik博士进行为期30个月的关于硝基化合物自由基反应的合作研究计划。这项研究将包括(1)探索烯丙基硝酸盐阴离子与2-卤代-2-硝基丙烷在光刺激下缺乏反应活性的原因(S)，以及(2)将基本的SRN1机制扩展到涉及脂肪族硝基化合物的电子转移反应的新型自由基链过程。还将研究受阻的酚氧自由基与被束缚的硝酸根阴离子发生环化反应的可能性。拟议的研究将试图扩大对某些与适当阴离子(亲核剂)的自由基链取代反应机理的一般理解。合作者是该提案领域备受尊敬的研究人员。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国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与工程基金会(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). ***
