(PtSi)x Aggregates from SiH Bond Activation

无机化学、生物无机化学和金属有机化学奖支持密苏里大学圣路易斯分校的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，目的是深入了解反应途径，并研究各种伯氢硅烷和次氢硅烷与低价富电子的后过渡金属络合物(如铂、Rh和Ir)的反应性，以更好地了解影响Si-H键活化的因素。将考察化学计量反应，涉及硅烷和硅烷上的空间受阻基团，其中SiH2基团并入杂环。更好地理解金属催化的反应，如硅氢化脱氢偶联、硅氢化和硅烷重分布等，对于未来新材料和新工艺的发展至关重要。这项研究将为学生提供机会学习过渡金属和有机硅化学这两个重叠的化学领域。学生将发展合成有机和有机金属的技能，运用大量的提纯、光谱和演示技术。

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.
