Organometallic Reaction Mechanisms

对有机金属反应机理的研究将继续进行。将研究协同有机金属反应，在这些反应中，原本会产生具有空配位位的高能中间体的基本步骤与消耗空配位位的步骤相结合。本文将仔细研究氯化氢加成于碳铼配合物的立体化学和烷基氯铼产物的重排。探索罕见金属-金属双键化合物的合成和反应。烃基桥接二铁化合物的研究已被证明在碳-碳键形成过程中很有用，将继续进行。间烷基二铁配合物的不寻常的光化学脱氢机理将得到特别的关注。在化学学部无机、生物无机和有机金属项目的这个项目中，威斯康星大学麦迪逊分校的查尔斯·凯西博士将继续研究有机金属反应的机制。这些研究将在均相催化和新的有用化合物的合成方面具有应用价值。

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.
