项目摘要

9311812 Dunbar With this award, the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on synthesis of compounds containing heavier transition metals by Dr. Kim R. Dunbar of the Chemistry Department, Michigan State University. Solvated mononuclear and dinuclear complexes with new phosphine ligands possessing unusual steric or electronic properties and with cyanide or polynitrile will be used as starting materials for the synthesis of unusual or unstable species. Targeted for synthesis are monomers of iridium, palladium, and platinum which contain seven d-electrons and which might have activity in radical coupling reactions. In addition, some iron(II) oligomers will be synthesized, using bulky ether-phosphines to stabilize the structure. Polynuclear metal nitriles of molybdenum, rhenium, rhodium, manganese and vanadium which may have unusual magnetic or electronic properties will be prepared. %%% Some metal ions associated only with solvent molecules are readily available for reaction with other species in solution which are able to substitute for the solvent molecule. Dr. Dunbar is able to prepare such species for a variety of second and third row transition metals, starting from dinuclear compounds. In this project, she will synthesize new solid-state inorganic compounds containing organophosphorus, organonitrile, and cyanide ligands. This research may result in new routes to unusual materials having useful solid state properties. ***

9311812 Dunbar 凭借该奖项，无机、生物无机和有机金属化学项目支持密歇根州立大学化学系 Kim R. Dunbar 博士对含有较重过渡金属的化合物的合成研究。具有不寻常空间或电子性质的新膦配体以及氰化物或多腈的溶剂化单核和双核配合物将用作合成不寻常或不稳定物质的起始材料。合成的目标是铱、钯和铂的单体，它们含有七个 d 电子，可能在自由基偶联反应中具有活性。此外，还将合成一些铁(II)低聚物，使用大体积的醚-膦来稳定结构。将制备可能具有不寻常的磁性或电子性质的钼、铼、铑、锰和钒的多核金属腈。 %%% 一些仅与溶剂分子缔合的金属离子很容易与溶液中能够替代溶剂分子的其他物质发生反应。邓巴博士能够从双核化合物开始为各种第二和第三行过渡金属制备此类物质。在这个项目中，她将合成含有有机磷、有机腈和氰化物配体的新型固态无机化合物。这项研究可能会为具有有用固态特性的不寻常材料开辟新途径。 ***
