Thermochemical, Kinetic and Catalytic Studies of Protonated Transition Metal Complexes

爱荷华州州立大学化学系的Robert J. Angelici博士得到化学系无机、生物无机和有机化学项目的支持（i）通过使用量热技术和强酸测量质子化率来确定各种金属络合物的碱度（三氟甲基磺酸）在有机介质中的碱性，（ii）了解金属和配体的性质对这些碱性的影响，以及（iii）研究了质子化作用对金属配合物催化反应的影响，并对几种金属配合物在金属中心的碱性进行了评价，为设计新型均相催化剂提供了理论依据催化剂，并将提供宝贵的热力学数据给其他化学家。一些学生和博士后助理将在许多金属配合物的合成和化合物的热力学和反应性的理解培训。

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.
