Synthesis and Reactivity of Mixed-Metal Gold Cluster Compounds

在该项目中，明尼苏达大学化学系的Louis H.Pignolet博士将研究含铂、钯和金的异核簇合物的合成、反应活性和表征。将合成含有不到13个金属原子和配体的新化合物，如异腈、烷基膦和卤离子。在某些情况下，还将引入第三种金属，如Rh、Om或Ni。此外，还将制备包含13个以上金属原子的更大的团簇。化合物将使用一些以前没有被用于团簇的方法进行表征，包括扫描隧道显微镜和等离子体解吸质谱。将在均相和非均相条件下测试化合物的催化性能。含有大量金属和混合金属的离散化合物由于其潜在的催化应用而被研究。它们可以作为许多商业催化剂的有效模型，这些催化剂是合金或金属混合物，或者它们本身可能被证明是有效的催化剂。

In this project supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, Dr. Louis H. Pignolet of the Chemistry Department, University of Minnesota, will investigate the synthesis, reactivity and characterization of heteronuclear cluster compounds containing platinum or palladium, and gold. New compounds that contain less than thirteen metal atoms and ligands such as isonitriles, alkyl phosphines, and halide ions will be synthesized. In some cases a third metal, such as rhodium, osmium, or nickel, will also be introduced. In addition, larger clusters containing more than thirteen metal atoms will be prepared. Compounds will be characterized using some methods that that have not been exploited previously for clusters, including scanning tunneling microscopy and plasma desorption mass spectrometry. Catalytic properties of the compounds will be tested, both under homogeneous and heterogeneous conditions. %%% Discrete compounds containing a large number of metals and a mixture of metals are being investigated because of their potential catalytic applications. They may serve as effective models for many commercial catalysts which are alloys, or mixtures of metals, or they may prove to be effective catalysts themselves.
