Solution Thermochemical Investigations of Organometallic Complexes

通过该奖项，无机、生物无机和有机金属化学项目支持新奥尔良大学化学系Steven P. Nolan博士的研究，以确定有机金属化合物的键强度。金属-配体键焓将主要测定参与均相催化的化合物的羰基键和膦键。将研究新型单齿和双齿膦和铁钌亚磷酸盐，以及钌铑羰基。此外，还将研究一些金属-碳、金属-氢和金属-硅的键焓。热力学数据为理解反应（包括催化反应）中的反应性提供了定量基础。可以预测新反应的可行性，优化新催化剂的设计。关于有机金属化合物的可用热力学数据是有限的。本研究将提供与重要工业催化剂相关的化合物中金属-碳键和金属-磷键断裂焓的基本信息。

With this award, the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research by Dr. Steven P. Nolan of the Chemistry Department, University of New Orleans, for studies to determine bond strengths in organometallic compounds. Metal-ligand bond enthalpies will be determined primarily for carbonyl and phosphine bonds for compounds involved in homogeneous catalysis. Novel mono- and bi-dentate phosphines and phosphites of iron and ruthenium, and ruthenium and rhodium carbonyls will be studied. In addition some metal-carbon, metal-hydrogen, and metal-silicon bond enthalpies will be investigated. Thermodynamic data provides a quantitative basis for understanding reactivity in reactions, including catalytic reactions. The feasibility of new reactions can be predicted and design of new catalysts can be optimized. The available thermodynamic data on organometallic compounds is limited. This research will provide basic information on the enthalpy for breaking metal-carbon and metal-phosphorus bonds in compounds related to those found in important industrial catalysts.
