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). ***

小行星9411164 该奖项提供资金，允许格伦博士。罗素，化学系，爱荷华州州立大学，继续与博士Woonphil Baik，化学系，明志大学，韩国，为期30个月，合作研究计划的自由基反应的硝基化合物。 本研究将涉及（1）探索光刺激时烯丙基硝膦酸根阴离子与2-卤代-2-硝基丙烷之间缺乏反应性的原因，以及（2）将基本SRN 1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。 实现环化反应的受阻酚自由基与拴系的硝态氮阴离子的可能性也将进行研究。 拟议的研究将试图扩大某些自由基链取代反应与适当的阴离子（亲核试剂）的机制的一般理解。 合作者是该提案领域备受尊敬的研究人员。 该项目与美国的目标有关-韩国合作科学计划，旨在通过科学信息，思想，技能和技术的交流以及通过互利问题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。 韩国对该项目的参与得到了韩国科学和工程基金会的支持。 ***
