项目摘要

Professor Dean Roddick of the University of Wyoming Chemistry Department is supported by the Inorganic, Bioinorganic and Organometallic Chemistry program for his inorganic chemistry studies on the synthesis of new perfluoroalkylphosphine (PFAP) supported metal cations, molecular ions that combine cationic metal centers, strongly-accepting ligands, and coordinative unsaturation to form "superelectrophiles", systems where metal electrophilicity is maximized. This PFAP metal coordination chemistry has provided a wide array of acceptor metal complexes that are electronically similar to carbonyl analogues. The combination of PFAP ligands with cationic or polycationic metal ions provides strongly electrophilic stable coordination complexes, "superelectrophiles", with applicability to challenging problems in coordination chemistry and catalysis, and practical applications in organic synthesis and the production of commodity chemicals and pharmaceuticals. Research in PFAP platinum coordination chemistry has resulted in the strongest (and least coordinating) superacid system known. This research will focus on the chemistry of new perfluoroalkylphosphine (PFAP) supported metal cations. Such metal-mediated electrophilic catalyst molecular species have practical applications in organic synthesis and the production of commodity chemicals and pharmaceuticals. The development of new classes of powerful metal electrophiles is relevant to alkane functionalization and conversion chemistry, with implications for a future chemical industry based on methane as a primary feedstock. Postdocs, graduate students and undergraduate students will receive multifaceted training in inorganic and organometallic synthesis and characterization.

怀俄明大学化学系的Dean Roddick教授得到了无机化学、生物无机化学和金属有机化学项目的支持，他的无机化学研究涉及合成新型全氟烷基膦(PFAP)负载的金属阳离子、结合阳离子金属中心的分子离子、强接受配体和配位不饱和形成“超亲电”，即金属亲电性最大化的体系。这种PFAP金属配位化学提供了广泛的受体金属络合物，它们在电子上类似于羰基类似物。PFAP配体与阳离子或多阳离子金属离子结合，形成了具有很强亲电性的稳定配位络合物，即“超亲电络合物”，可用于解决配位化学和催化方面的难题，以及在有机合成、日用化学品和药品生产中的实际应用。对PFAP铂配位化学的研究产生了已知的最强(和最少配位)的超强酸体系。本研究将重点研究新型全氟烷基膦(PFAP)负载金属阳离子的化学。这类金属介导型亲电催化剂分子物种在有机合成以及日用化学品和药品的生产中具有实际应用。新型高效金属亲电剂的发展与烷烃官能化和转化化学有关，对未来以甲烷为主要原料的化学工业具有重要意义。博士后、研究生和本科生将接受无机和有机金属合成和表征方面的多方面培训。
