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.

对有机金属反应机理的研究将继续进行。将考察协调的有机金属反应，在这些反应中，原本会产生具有空位配位的高能中间体的基本步骤与消耗空位配位的步骤相结合。我们将仔细研究氯化氢加成榄卡宾络合物的立体化学和烷基氯锗产物的重排。本课程将探讨特殊金属-金属双键化合物的合成和反应。碳氢桥联二铁化合物的研究将继续进行，这些化合物已被证明在碳-碳键形成过程中有用。间亚烷基二铁络合物的一种不寻常的光化学脱氢的机理将受到特别关注。在化学系无机、生物无机和有机金属项目中，麦迪逊威斯康星大学的Charles Casey博士将继续研究金属有机反应的机理。这些研究将应用于均相催化和合成新的有用的化合物。
