Pressure, Temperature, and Medium Effect Studies of Transition Metal Reactions

该奖项在无机、生物无机和有机金属项目中支持博士的工作。华盛顿州立大学化学系的scott E. whland, John P. Hunt和Harold W. Dodgen研究压力对非水溶液中电子转移反应的影响。研究中选择的特定体系包括茂金属、一系列铬异腈和防取代的螯合物。主要的研究方法将是停止流动和核磁共振。除了压力，温度依赖，溶剂变化和离子强度将被研究。在低温下可以观察到溶剂或电子隧穿的速率控制。这个项目可以增加对非水介质中氧化还原反应的基本性质的理解，并影响这一领域的理论发展。这一结果对有机金属化学、催化反应和一些涉及细胞膜的生物过程也很有用。了解溶剂的作用可以通过溶剂的变化来控制反应速率。

This award in the Inorganic, Bioinorganic, and Organometallic Program supports the work of Drs. Scot E. Wherland, John P. Hunt, and Harold W. Dodgen of the Chemistry Department, Washington State University, for the study of the effect of pressure on electron transfer reactions in nonaqueous solutions. Specific systems chosen for study include metallocenes, a series of chromium isonitriles, and substitution-proof clathrochelates. The primary methods of investigation will be stopped-flow and NMR. In addition to pressure, temperature dependence, solvent variation, and ionic strength will be studied. Rate control by solvents or electron tunneling at low temperatures may be observed. %%% This project may increase understanding of the fundamental nature of oxidation-reduction reactions in nonaqueous media and influence theoretical development in this area. The results would also be useful for organometallic chemistry, catalytic reactions, and some biological processes involving cell membranes. An understanding of the role of solvents could lead to some control of reaction rates by solvent variation.
