New Modes of Metallacycle and Carbene Reactivity

在这个由无机化学、生物无机化学和金属有机化学计划支持的项目中，加州大学圣地亚哥分校的约瑟夫·M·奥康纳将继续在金属环和卡宾化学交界处的有机金属研究领域进行研究。这项研究直接影响到金属卡宾在烯烃歧化反应、烯烃和炔烃聚合、环丙烷化化学以及一系列令人印象深刻的合成有机方法学中的作用。拟议的研究重点是铱、铑和钴化合物，以及开发新的卡宾偶联反应，在该反应中，上述金属的扩环金属环以及最终的四元和五元碳环将是可获得的。除了综合研究外，还将进行结构和力学研究。

In this project supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, Joseph M. O'Connor of the University of California, San Diego will continue studies in the area of organometallic research at the interface of metallacycle and carbene chemistry. This research directly impinges on the role of metal carbenes in alkene metathesis, alkene and alkyne polymerization, cyclopropanation chemistry and an impressive array of synthetic organic methodology. The proposed research has its focus on iridium, rhodium and cobalt compounds and the development of new carbene coupling reactions wherein ring-expanded metallacycles of the above metals and ultimately four- and five-membered carbocycles would be accessible. In addition to the synthetic studies, structural and mechanistic studies will also be carried out.
