Chemistry of Transition Metal/Main Group Element Complexes

无机化学、生物无机化学和金属有机化学项目的重点是过渡金属/主族元素化合物的结构、成键和反应活性。许多工作利用手性稀土配合物作为模板，这种配合物很容易以光学活性的形式获得。这有利于在不对称合成中进行机械测试和应用研究结果。具体目标包括合成和研究(1)烷基卤化物络合物，这是一类几乎未知的化合物；(2)不饱和有机硅配体的络合物，如硅烯、二硅烯和硅烯络合物；以及(3)磷化物、酰胺和亚硫氧化物络合物。将有可能开发出用于烷基卤化物活化和硫化物不对称氧化的通用方法。磷和硅的分子化学的基础研究很重要，因为这些主要族元素在材料科学(光刻胶、陶瓷、复合材料等)中有许多用途，通常与金属结合在一起。

The focus of this project in the Inorganic, Bioinorganic and Organometallic Chemistry Program is structure, bonding and reactivity in transition metal/main group element compounds. Much of the work utilizes as a template a chiral rhenium complex, which is readily available in optically active form. This facilitates mechanistic tests and application of the findings in asymmetric synthesis. Specific goals include the synthesis and study of (1) alkyl halide complexes, a virtually unknown class of compounds; (2) complexes of unsaturated organosilicon ligands, such as silylene, disilene and silene complexes; and (3) phosphido, amide and sulfoxide complexes. It is probable that general methods for the activation of alkyl halides and for asymmetric oxidation of sulfides will be developed. Basic research on the molecular chemistry of phosphorus and silicon is important because of the many uses which these main group elements find in materials science (photoresists, ceramics, composits, etc.), often in combination with a metal.
