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

这一无机化学、生物无机化学和金属有机化学项目的奖项继续支持麻省理工学院化学系理查德·R·施罗克博士对催化反应机理的研究。将继续进行四个方面的调查。将继续努力合成钼催化剂，以生产用于双烯环合复分解反应的对映体纯产品。其次，将研究含有新的硼基取代二胺配体的络合物的有机金属化学，以测试这些物种对α-烯烃聚合的活性。第三个研究领域比较了含钼和含钨的三胺胺络合物的反应性。第四个项目涉及含有平面三酰胺配体的新配合物的合成和反应。催化剂在特定反应产物的合成中很重要，它们的使用可以显著节省能源和化学物质。这项工作的目标是系统地设计附着在活性金属中心上的基团，以便控制它们的催化效果。所研究的特定体系包含氮基(氨基)配体和早期过渡金属。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program continues support for studies of catalytic reaction mechanisms by Dr. Richard R. Schrock of the Chemistry Department, Massachusetts Institute of Technology. Four areas of investigation will be pursued. Efforts to synthesize molybdenum catalysts that produce enantiomerically pure products for ring closing metathesis of dienes will be continued. Second, the organometallic chemistry of complexes containing a new boryl-substituted diamido ligand will be studied in order to test the activity of such species for the polymerization of alpha-olefins. The third area of investigation compares the reactivity of triamidoamine complexes containing molybdenum to those containing tungsten. The fourth project involves the synthesis and reactions of new complexes containing a planar triamido ligand. Catalysts are important in the synthesis of specific reaction products and their use can result in significant energy and chemical savings. The goal of this work is to systematically design groups attached to active metal centers in order to control their catalytic effects. The specific systems studied contain nitrogen-based (amido) ligands and early transition metals.
