Multiple Metal-Carbon Bonds, Metallacycles, and Catalytic Reactions Involving Olefins & Acetylenes

无机，生物无机和有机化学计划支持教授理查德R。Schrock，用于研究含有钼或钨的单醇盐吡咯烷（MAP）催化剂。 MAP催化剂由于其异常高的反应性和其利用金属中心的手性的能力而在烯烃复分解中非常有用。 这些催化剂比前几代催化剂更稳定，寿命更长，反应性更强。 这项研究的重点是最大限度地提高微妙的空间相互作用的配体配位球。 新型多相催化剂是通过附着在二氧化硅载体上而制备的。 含有多个金属-碳键的化合物的高氧化态化学在学术和工业环境中对有机、聚合物、药物和材料化学都有重大影响。

The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the efforts of Professor Richard R. Schrock for the study of MonoAlkoxide Pyrrolide (MAP) catalysts that contain molybdenum or tungsten. MAP catalysts are very useful in olefin metathesis due to their unusually high reactivity and their ability to exploit the chirality of the metal center. These catalysts are much more stable, long-lived and reactive than previous generations. This research focuses on maximizing the subtle steric interactions of the ligand coordination sphere. New heterogeneous catalysts are prepared by attachment to silica supports. The high oxidation state chemistry of compounds containing multiple metal-carbon bonds has a significant impact on organic, polymer, pharmaceutical and materials chemistries both in academic and industrial settings.
