The objective of this project is the development of a fundamental understanding of how dynamic interactions involving microemulsion constituents, catalytic films, and reactants influence reaction rates in electrochemical systems. Results will guide the development of new electrodes and reaction systems designed specifically for microemulsions. Electrochemical addition and cyclization reactions will be targeted for ultimate application to the synthesis of fine chemicals including lactones, pheromones, and optically active olefins and alcohols. A key issue to be addressed is the influence of micellized surfactant within catalytic polymer layers on catalyst formal potentials and catalytic activity. New catalytic electrodes specifically for carbon-carbon bond forming syntheses in microemulsions will be developed. Effects of property-altering modifications of polylysine-cobalt complex films will be explored. Compositions of microemulsions and properties of catalytic coatings will be tuned for best reaction rates and pathways for key reactions. The broad impact of this work will be to provide fundamental guidance for the design of efficient mediated electrochemical synthetic processes in relatively inexpensive, low toxicity, water based media.

该项目的目标是对涉及微乳液成分、催化膜和反应物的动态相互作用如何影响电化学系统的反应速率有一个基本的了解。 结果将指导专为微乳液设计的新电极和反应系统的开发。 电化学加成和环化反应将最终应用于精细化学品的合成，包括内酯、信息素、光学活性烯烃和醇。 需要解决的一个关键问题是催化聚合物层内胶束化表面活性剂对催化剂形式势和催化活性的影响。 将开发专门用于微乳液中碳-碳键形成合成的新型催化电极。将探讨聚赖氨酸-钴复合膜的性质改变修饰的影响。 微乳液的成分和催化涂层的性能将被调整以获得最佳的反应速率和关键反应的途径。 这项工作的广泛影响将为在相对便宜、低毒的水基介质中设计高效介导的电化学合成过程提供基本指导。
