The underlying theme of this project in the Inorganic, Bioinorganic and Organometallic Chemistry Program is the chemical elucidation of highly reactive species and the study of products derived therefrom. Metal vapor and conventional synthetic methodology will be employed to prepare fluorocarbon complexes of early transition metals. Trapping of metallic and molecular clusters will be accomplished by solvation and/or ligand injection during cluster growth in low temperature solvents. Further elucidation of bimetallic solvated metal atom dispersed (SMAD) catalysts will be carried out using structure sensitive reaction chemistry coupled with spectroscopic probes, especially EXAFS, Mossbauer and XPS techniques. In order to develop the highly reactive synthon CS to its full potential, attempts will be made to synthesize precursors which evolve CS at relatively elevated temperatures. Several of the substances under study in this project have potential for industrial applications. Of particular interest in this connection are the metal atom clusters of carefully-controlled size and the highly reactive SMAD catalysts.

该项目在无机、生物无机和有机金属化学项目中的基本主题是高活性物质的化学阐明以及由此衍生的产品的研究。将采用金属蒸气和常规合成方法来制备早期过渡金属的碳氟化合物。金属和分子簇的捕获将通过簇在低温溶剂中生长期间的溶剂化和/或配体注入来完成。双金属溶剂化金属原子分散（SMAD）催化剂的进一步阐明将使用结构敏感反应化学与光谱探针相结合，特别是 EXAFS、Mossbauer 和 XPS 技术。为了充分发挥高反应性合成子CS的潜力，将尝试合成在相对较高的温度下放出CS的前体。 该项目正在研究的几种物质具有工业应用的潜力。在这方面特别令人感兴趣的是精心控制尺寸的金属原子簇和高反应性 SMAD 催化剂。
