Thermochemical, Kinetic and Catalytic Studies of Protonated Transition Metal Complexes

爱荷华州立大学化学系Robert J.Angelici博士得到化学部无机、生物无机和有机金属化学项目的支持：(I)通过使用量热技术和有机介质中的非常强的酸(三氟甲磺酸)测量质子化热来确定各种金属络合物的碱性，(Ii)了解金属和配体的性质对这些碱性的影响，以及(Iii)考察质子化对这些金属络合物反应的促进作用，这可能有助于设计新的均相催化剂。所提出的工作旨在评估几种金属络合物在金属中心的碱性，这将被证明对新的均相催化剂的设计有用，并将为其他化学家提供宝贵的热力学数据。几名学生和博士后助理将接受许多金属络合物的合成方面的培训，并了解化合物的热力学和反应性。

Dr. Robert J. Angelici, Department of Chemistry, Iowa State University is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program of the Chemistry Division (i) to determine the basicities of various metal complexes by measuring enthalpies of protonation using calorimetric techniques and a very strong acid (trifluoromethylsulfonic acid) in organic media, (ii) to understand the influence of the nature of the metal and the ligands on these basicities, and (iii) to examine the effects protonation has on promoting reactions of these metal complexes that might be useful in the design of new homogeneous catalysts.The work proposed seeks to assess the basicities of several metal complexes at the metal centers which will prove useful to the design of new homogeneous catalysts and will provide invaluable thermodynamic data to other chemists. Several students and post-doctoral associates will be trained in the synthesis of many of the metal complexes and in the understanding of the thermodynamics and reactivities of compounds.
