Hydrocarbon Activation and Decarbonylation Chemistry of Iridium and Ruthenium Fluoroalkylphosphine Complexes

该奖项来自无机、生物无机和有机金属化学项目，支持怀俄明州大学化学系Dean M. Roddick博士对烷烃功能化的研究。将研究（氟烷基）膦配体的铱配合物催化环烷烃脱氢活性，在某些情况下，将确定反应的机理。本文将合成新的含弱配位体的铱配合物和新的氢化钌化合物，并对其烷烃活化反应性进行研究。由于（氟烷基）膦配体在酸性和氧化条件下的稳定性，将研究C-H活化后的氢清除、烯烃氧化或直接金属-烷基氧化的可能性。这类化合物对催化醛和醇脱碳的适用性也将进行测试。与金属相连的氟化烷基膦基团从金属附近的电子电荷中吸取电荷，但不像其他基团也能做到这一点，它耐热或氧化降解。%%%由于这种稳定性，合成的化合物在设计功能化烷烃的试剂和催化剂方面具有实际应用的潜力。石油和天然气技术将受到成功结果的影响。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on alkane functionalization by Dr. Dean M. Roddick of the Chemistry Department, University of Wyoming. Iridium complexes of (fluoroalkyl)phospine ligands will be surveyed for catalytic cycloalkane dehydrogenation activity and, in some cases, the mechanism of the reaction will be determined. New iridum complexes containing weakly coordinating ligands and new ruthenium hydride compounds will by synthesized and examined for alkane activation reactivity. Because of the stability of (fluoroalkyl)phospine ligands in acidic and in oxidizing conditions, the possibility of C-H activation followed by hydrogen scavenging, olefin oxidation or direct metal-alkyl oxidations will be investigated. The suitability of this class of compounds for catalytic aldehyde and alcohol decarbonylation will also be tested. %%% The fluoronated alkylphosphine group which is attached to the metal withdraws electronic charge from the vicinity of the metal but, unlike other groups which can also accomplish this, is resistant to thermal or oxidative degradation. Because of this stability, the compounds synthesized have potential for practical use in the design of reagents and catalysts to functionalize alkanes. Petroleum and natural gas technology would be influenced by a successful outcome.
