U.S.-Federal Republic of Germany Cooperative Research in theStudy of Alkyl Propargyl Biradicals

该奖项支持洛克菲勒大学的William C. Agosta博士与汉堡大学的Paul Margaretha博士合作。他们在烷基丙炔双基化学方面有共同的兴趣和互补的专业知识，他们的联合工作强调新的机制研究和形成这些物种的新方法。洛克菲勒小组主要由博士后组成，在一般机械有机光化学和小环化合物的合成和表征方面具有专业知识。规模较大的汉堡集团提供定量测量和自由基反应动力学、电化学和有机氟化学方面的专业知识。由于研究生人数较多，因此能够更好地进行需要更多人力的研究。几年来，他们在北约的赞助下进行了卓有成效的合作。在美国国家科学基金会（NSF）的支持下，他们将合作研究二氧化碳中的氢迁移机制、二氧化碳2的独立繁殖、酮15a的光化学性质及生成烷基丙炔双自由基的分子内探索反应。这项合作安排将加强Agosta博士的国内研究，旨在了解有机光化学反应机制中的结构和立体化学控制因素，并利用受控光化学过程构建理论和结构感兴趣的新型有机环系统。

This award supports Dr. William C. Agosta of the Rockefeller University to collaborate with Dr. Paul Margaretha of the University of Hamburg. They have a mutual interest and complementary expertise in the chemistry of alkyl propargyl biradicals, and their joint work emphasizes novel mechanistic studies and new methods of forming these species. The small Rockefeller group is composed primarily of postdoctoral workers, and has expertise in general mechanistic organic photochemistry and the synthesis and characterization of small ring compounds. The larger Hamburg group offers expertise in quantitative measurement and the kinetics of radical reactions, electrochemistry and organofluorine chemistry. Because of a larger number of graduate students, it is better able to carry out studies requiring greater manpower. They have collaborated very productively for several years under NATO sponsorship. Under support from the National Science Foundation (NSF) they will collaborate in studies of the mechanism of hydrogen migration in carbene, the independent propagation of carbene 2, the photochemistry of ketone 15a and exploratory intramolecular reactions leading to alkyl propargyl biradicals. This cooperative arrangement will enhance Dr. Agosta's domestic research which is directed at understanding structural and stereochemical control factors in organic photochemical reaction mechanisms, and using controlled photochemical processes for the construction of novel organic ring systems of theoretical and structural interest.
