有机金属反应机理的研究将是 持续期间内的协调的有机金属反应将被检查 在这些基本步骤中， 具有空配位点的能量中间体联合收割机 使用占用空闲协调站点的步骤。的 氯化氢加成反应立体化学 碳烯配合物和烷基氯的重排 将仔细研究这些产品。合成和 不寻常的金属-金属双键化合物的反应将 将被探索。 烃基桥联二铁的研究 化合物，已被证明可用于碳-碳 债券形成过程，将继续进行。 的机制， 间亚烷基二铁的不寻常的光化学脱氢 综合体将受到特别关注。 %%% 在这个项目中，无机，生物无机和有机- 化学部金属计划，查尔斯凯西博士 位于麦迪逊的威斯康星州大学将继续研究 有机金属反应的机理。 这些研究 将应用于均相催化， 合成新的有用的化合物。

Studies of the mechanisms of organometallic reactions will be continued. Concerted organometallic reactions will be examined in which elementary steps that would otherwise generate high energy intermediates with vacant coordination sites combine with steps that consume vacant coordination sites. The stereochemistry of addition of hydrogen chloride to rhenium carbene complexes and the rearrangements of the alkyl chloro rhenium products will be carefully studied. The synthesis and reactions of unusual metal-metal double-bonded compounds will will be explored. Studies of hydrocarbyl bridged diiron compounds, which have proven useful in carbon-carbon bond-forming processes, will be continued. The mechanism of an unusual photochemical dehydrogenation of a m-alkylidene diiron complex will receive special attention. %%% In this project in the Inorganic, Bioinorganic, and Organo- metallic Program of the Chemistry Division, Dr. Charles Casey of the University of Wisconsin, Madison, will continue studies of the mechanisms of organometallic reactions. These studies will have application to homogeneous catalysis and the synthesis of new and useful compounds.
