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.

该奖项由无机、生物无机和有机金属化学项目颁发，支持康奈尔大学的Peter T. Wolczanski的研究，该研究旨在研究铌和钽配合物与三叔丁基氧化硅（silox）配体催化烯烃-烷基胺重排的机理和热力学。硅烷的硫类似物将用于探索连接锰、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-氧衍生物进行探讨。方平面钨（IV）硅烷衍生物的基本配位和有机金属化学将被研究与d8配合物在氧化加成反应中的反应性。有机金属配合物与硅基配体的反应将被研究，以解决这些反应如何进行的基本问题。
