项目摘要

9305492 Nolan With this award, the Inorganic, Bioinorganic, and Organometallic Chemistry Program provides support for determining bond enthalpies of organometallic compounds by Dr. Steven P. Nolan of the Chemistry Department, University of New Orleans. Metal-hydride, metal-alkyl, metal-arene, metal-diene, metal-phosphine, and metal-metal bond energies of group 8 metals will be found using solution calorimetric methods. Special emphasis will be placed on iron and ruthenium complexes of interest in homogeneous catalysis. For example, tetracarbonyliron derivatives will be used in the determination of olefin-iron bond strengths and cyclopentadienylruthenium species will be used to investigate a series of diene-ruthenium bonds. Attempts will be made to determine bond strengths of ruthenium with heterocyclic compounds which are relevant to hydrodenitrogenation, hydrodesulfurization, and hydrosilation. %%% Thermodynamic data are fundamentally important for both theoretical and applied research in organometallic chemistry and catalysis, yet relatively little data are available on Group 8 organometallic bond strengths. Knowing the energetics of steps in a catalytic reaction is valuable for the development of new and more effective catalysts useful, for example, in hydroformylation or alkene isomerization reactions in the chemical industry. ***

9305492 Nolan 凭借该奖项，无机、生物无机和有机金属化学项目为新奥尔良大学化学系的 Steven P. Nolan 博士确定有机金属化合物的键焓提供了支持。第 8 族金属的金属氢化物、金属-烷基、金属-芳烃、金属-二烯、金属-膦和金属-金属键能将使用溶液量热法求出。将特别强调均相催化中感兴趣的铁和钌络合物。例如，四羰基铁衍生物将用于测定烯烃-铁键强度，环戊二烯基钌物种将用于研究一系列二烯-钌键。将尝试确定钌与与加氢脱氮、加氢脱硫和硅氢加成相关的杂环化合物的键强度。 %%% 热力学数据对于有机金属化学和催化的理论和应用研究至关重要，但有关第 8 族有机金属键强度的数据相对较少。了解催化反应中各步骤的能量对于开发新的、更有效的催化剂非常有价值，例如可用于化学工业中的加氢甲酰化或烯烃异构化反应。 ***
