The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the research of Professor Kenneth J. Caulton for the synthesis, characterization and reactivity testing of strong chemical bonds (multiple bonds and unreactive bonds). The strategy is to build high kinetic and thermodynamic reactivity into transition metal complexes while leaving metal orbitals unused and suited to attach and modify small substrate molecules. The target molecules violate textbook principles by having radical character, and thus fall outside the predictive capacity of current thinking. The far reaching implications of the research include: 1) the possible increase in control of normally unselective radical reactions, 2) the ability to make molecules capable of reacting with even the most inert of substrates: alkanes, N2O, CO2 and fluorocarbons, and 3) the pioneering access to unusual metal oxidation states and unusual electron transfer reactions. In general, the studies impact chemical catalysis with regard to fewer by-products, greater synthetic control and decreased energy consumption.

无机、生物无机和有机金属化学项目支持Kenneth J. Caulton教授对强化学键（多键和非反应键）的合成、表征和反应性测试的研究。该策略是在过渡金属配合物中建立高动力学和热力学反应性，同时保留未使用的金属轨道，适合附着和修饰小底物分子。目标分子具有激进的性质，违反了教科书的原则，因此超出了当前思维的预测能力。该研究的深远影响包括：1)可能增加对通常非选择性自由基反应的控制，2)使分子能够与最惰性的底物反应的能力：烷烃，N2O， CO2和氟碳化合物，以及3)开创性地获得不寻常的金属氧化态和不寻常的电子转移反应。总的来说，这些研究在减少副产物、加强合成控制和减少能源消耗方面影响了化学催化。
