Organometallics in Superacidic Media

怀俄明大学的罗迪克院长得到了无机化学、生物无机化学和金属有机化学计划的支持，继续致力于在超酸性环境中研究有机金属化合物。使用氟化的螯合膦，如二(全氟乙基膦)乙烷(Dfepe)，Roddick制备了在超酸性溶液中稳定的铂烷基，如(Dfepe)铂(Me)(OTf)和[(Dfepe)铂(Me)(CO)]。将制备一系列烷基以确定其相对的蛋白质分解稳定性。该化学将被扩展到探索金属配位球中的碳正离子化学。氢化物、多氢化合物和二氢络合物也将在这种独特的环境中进行研究。高压核磁共振和ATR-IR将被用来研究这些非常亲电的化合物与甲烷、氙气、氮和氧等弱碱的相互作用。这项工作探索了极端超强酸环境下有机金属化学的极限。超亲电性金属络合物提供了对金属表面烷烃转化的洞察。这种转化在石油裂解和其他重要的工业过程中是至关重要的。

Dean Roddick, University of Wyoming, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for continued work on organometallic compounds in superacidic environments. Using fluorinated chelating phosphines such as di(perfluoroethylphosphino)ethane (dfepe), Roddick has prepared platinum alkyls such as (dfepe)Pt(Me)(OTf) and [(dfepe)Pt(Me)(CO)]+ that are stable in superacidic solutions. A range of alkyls will be prepared to determine the relative proteolytic stability. The chemistry will be extended to explore carbenium ion chemistry in the coordination sphere of a metal. Hydrides, polyhydrides and dihydrogen complexes will also be studied in this unique environment. High pressure NMR and ATR-IR will be used to survey the interactions of these very electrophilic compounds with weak bases such as methane, xenon, nitrogen and oxygen.This work explores the limits of organometallic chemistry in the extreme superacid environment. The superelectrophilic metal complexes provide insight into alkane transformations on metal surfaces. Such transformations are critical in petroleum cracking and other important industrial processes.
