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.

怀俄明州大学的罗迪克院长得到了无机、生物无机和有机化学项目的支持，继续研究超酸性环境中的有机金属化合物。使用氟化螯合膦如二（全氟乙基膦基）乙烷（dfepe），罗迪克已经制备了在超酸性溶液中稳定的烷基铂如（dfepe）Pt（Me）（OTf）和[（dfepe）Pt（Me）（CO）]+。将制备一系列烷基以测定相对蛋白水解稳定性。化学将扩展到探索碳正离子化学在金属的配位领域。氢化物，多氢化物和二氢复合物也将在这个独特的环境中进行研究。高压NMR和ATR-IR将用于研究这些非常亲电的化合物与弱碱如甲烷、氙、氮和氧的相互作用，这项工作探索了金属有机化学在极端超强酸环境中的极限。超亲电金属配合物提供了深入了解金属表面上的烷烃转化。这种转化在石油裂化和其他重要的工业过程中至关重要。
