This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Dr. Janet Braddock-Wilking at the University of Missouri at St. Louis on transformations that occur between organosilanes and late transition metal complexes in order to obtain insight into the reaction pathways and to investigate the reactivity of a variety of primary and secondary hydrosilanes with low-valent electron-rich late transition metal complexes of metals such as Pt, Rh, and Ir to gain a better understanding of the factors that influence Si-H bond activation. Stoichiometric reactions will be examined that involve silanes with sterically hindered groups at silicon and silanes where the SiH2 group is incorporated into a heterocycle. A better understanding of how metal-catalyzed reactions such as dehydrocoupling of hydrosilanes, hydrosilylation, and silane redistribution occur is crucial for the future development of new materials and processes. The research will provide students with the opportunity to learn about two overlapping areas of chemistry, transition metal and organosilicon chemistry. Students will develop synthetic organic and organometallic skills, utilize a number of purification, spectroscopic and presentation techniques.

这个奖在无机，生物无机和有机物化学计划支持圣路易斯密苏里州大学的Janet Braddock-Wilking博士对有机硅烷和后过渡金属络合物之间发生的转化的研究，以深入了解反应途径，并研究各种伯和仲氢硅烷与低价电子的反应性。丰富的后过渡金属络合物的金属，如铂，铑，和铱，以获得更好的理解的因素，影响Si-H键活化。 将检查涉及在硅上具有空间位阻基团的硅烷和其中SiH 2基团并入杂环中的硅烷的化学计量反应。 更好地了解金属催化反应，如氢硅烷的脱氢偶联，氢化硅烷化和硅烷再分布是如何发生的，对于新材料和新工艺的未来发展至关重要。 这项研究将为学生提供机会，了解化学，过渡金属和有机硅化学的两个重叠领域。 学生将发展合成有机和有机金属的技能，利用一些纯化，光谱和演示技术。
