Polyoxoanion-Supported Transition Metals: Synthesis, Characterization and Applications in Catalysis

科罗拉多州立大学化学系的理查德·G·芬克博士在无机化学、生物无机化学和金属有机化学项目中获得这一奖项，以支持对多金属氧酸盐的研究和教育。新类型的多金属氧酸盐将被合成、表征并作为氧化催化剂进行测试。详细的动力学和机械学研究将包括在内。将开发使用多金属氧酸盐来支撑用于催化的有机金属衍生物的方法。此外，还将探索一种利用分子氧和醛作为重要烯烃氧化的辅助催化剂的新方法，如丙烯和乙烯。多金属氧酸盐阴离子是复杂的带负电荷的基团，包含许多金属原子，如钨和钛、氧原子和磷。在本研究中，我们将合成并开发新的这类阴离子作为氧化催化剂。这些物种的健壮性和惰性使它们有利于这一应用，而使用分子氧作为氧化剂的方法对环境无害。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research and education on polyoxometalates by Dr. Richard G. Finke of the Chemistry Department, Colorado State University. New classes of polyoxometalates will be synthesized, characterized, and tested as oxidation catalysts. Detailed kinetic and mechanistic studies will be included. Methods will be developed to use the polyoxometalates to support organometallic derivatives for catalytic use. Also, a novel method for using molecular oxygen and aldehyde as co-catalysts for oxidation of important olefins such as propylene and ethylene will be explored. Polyoxometalate anions are complex, negatively-charged groups which contain a number of metal atoms, such as tungsten and titantium; oxygen atoms; and phosphorus. In this research, new classes of these anions will be synthesized and developed as oxidation catalysts. The robustness and inertness of these species make them advantageous for this application, and an approach which uses molecular oxygen as an oxidant is environmentally benign.
