This award from the Inorganic, Bioinorganic and Organometallic Chemistry Program is in the area of organometallic chemistry. The focus of the project is the chemistry of transition metal compounds in which two metal atoms are bridged by an oxygen atom. The results of the project are expected to provide a better understanding of the behavior of an important class of industrial catalysts, namely heterogeneous catalysts in which small metal crystallites are supported on the surfaces of such metal oxides as alumina and silica. The objective of the project is to develop the chemistry of Group VIII transition metal complexes having bridging oxo, amido and imido ligands. The research will focus on the preparation and reactivity of mixed-metal mu-oxo complexes that model metal-support interactions of oxide supported heterogeneous catalysts, and on the reactivity of mu-amido and mu-imido ligands relevant to catalytic processes that could involve these functionalities. Appropriate complexes with these bridging ligands will be prepared, and their reactivity will be investigated, with emphasis on reactions that involve directly the M-O and M-N linkages in the compounds.

该奖项来自无机、生物无机和有机金属化学项目，属于有机金属化学领域。 该项目的重点是过渡金属化合物的化学，其中两个金属原子通过氧原子桥接。该项目的结果预计将有助于更好地了解一类重要工业催化剂的行为，即多相催化剂，其中小金属微晶负载在氧化铝和二氧化硅等金属氧化物的表面上。 该项目的目标是开发具有桥接氧代、酰胺基和亚氨基配体的第VIII族过渡金属配合物的化学性能。该研究将重点关注模拟氧化物负载非均相催化剂的金属-载体相互作用的混合金属mu-氧配合物的制备和反应性，以及与可能涉及这些的催化过程相关的mu-酰胺基和mu-酰亚胺配体的反应性。功能。将制备具有这些桥连配体的适当配合物，并研究它们的反应性，重点是直接涉及化合物中 M-O 和 M-N 连接的反应。
