Inorganic Redox Processes in Solution

在化学学部无机、生物无机和有机金属项目中，Gould将研究溶液中氧化还原反应的机制。重点将放在不常见的氧化态的参与上。化学思维的一个重要基础是对元素氧化态行为的广泛了解。主要研究三个方面：1)分子内配体到金属氢化物的迁移，导致金属中心的双电子还原；2)稳定铬（IV）的氧化还原化学，特别是通过使用双电子还原剂形成铬（III）的非互补反应；3)钼（III）和-(IV)的氧化还原化学。将尝试区分这些态的单电子氧化和双电子氧化；将寻找配体桥接的证据。所获得的数据应允许估计与这些系统有关的电子自交换率。

In this project in the Inorganic, Bioinorganic, and Organometallic Program of the Chemistry Division, Gould will study the mechanisms of oxidation-reduction reactions in solution. Emphasis will be placed on the participation of less usual oxidation states. One of the important foundations of chemical thinking is a broad knowledge of the behavior of the oxidation states of the elements. Three general areas will be investigated: 1) intramolecular ligand-to-metal hydride migrations, resulting in two-electron reductions of the metal center; 2) redox chemistry of stabilized chromium(IV), particularly the noncomplementary reactions in which chromium(III) is formed through the use of two-electron reducing agents; and 3) redox chemistry of molybdenum(III) and -(IV). Attempts will be made to differentiate one- and two-electron oxidations of these states; evidence for ligand bridging will be sought. The data obtained should allow estimates for rates of electron self-exchange pertaining to these systems.
