Small Molecule Activation and Coordination Chemistry

这项由无机化学、生物无机化学和金属有机化学项目颁发的奖项支持康奈尔大学的Peter T.Wolczanski的研究，该研究旨在研究具有三叔丁基硅氧化物(SILOX)配体的Nb和Ta配合物催化的烯烃-亚烷基重排反应的机理和热力学。硅氧烷的硫类似物将被用来探索连接的锰、铁、钴和镍四面体的二级结构，以探索生物启发的有机金属化学。涉及氧原子转移的电子因素将用硅-铼-氧衍生物来探索。我们将研究方形平面钨(IV)硅氧烷衍生物的基本配位和有机金属化学，以寻找与d8配合物在氧化加成反应中的相似之处。将研究有机金属配合物与硅基配体的反应，以解决这些反应如何进行的基本问题。

This award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Peter T. Wolczanski of Cornell University to study the mechanism and thermodynamics of olefin-alkylidine rearrangements catalyzed by niobium and tantalum complexes with tris-tertbutyl silicon oxide (silox) ligands. The sulfur analog of silox will be used to explore the secondary structures of linked manganese, iron, cobalt and nickel tetrahedra to explore bio-inspired organometallic chemistry. Electronic factors involving oxygen-atom transfer are to be explored with silox-rhenium-oxo derivatives. The fundamental coordination and organometallic chemistry of square planar tungsten(IV) silox derivatives will be investigated for reactivity parallels with d8 complexes in oxidative addition reactions.Reactions of organometallic complexes with silicon-based ligands will be studied to address fundamental questions as to how these reactions proceed.
