Electrophilic d-zero Metal Alkyl Complexes

这个奖项是在无机、生物无机和有机金属化学项目中颁发给爱荷华大学的，以支持理查德·f·乔丹的研究。本课题主要研究亲电性金属烷基配合物的合成、反应机理及其催化应用。这种配合物被认为是商用齐格勒-纳塔烯烃聚合催化剂中的活性物质。将探索四个新的研究领域。(1)有机锆和铪烷基配合物的结构和动力学；(2)阳离子配合物的插入和β - h消除反应机理，重点研究配体结构/反应性关系；(3)催化生成配体C-H活化/C-C偶联反应，包括手性催化剂的立体选择反应；(4)含碳硼烷配体的新型亲电金属烷基催化剂的合成与化学研究。这些研究将为Ziegler-Natta催化机理、新型碳氢活化化学和不对称催化以及新型亲电金属烷基配合物的机理研究和合成应用提供新的见解。

This award is made in the Inorganic, Bioinorganic and Organometallic Chemistry Program to the University of Iowa in support of the research of Richard F. Jordan. The main theme of the research is the synthesis, reaction mechanisms, and catalytic applications of electrophilic metal alkyl complexes. Such complexes are believed to be the active species in commercial Ziegler-Natta olefin polymerization catalysts. Four new areas of research will be probed. (1) The structures and dynamics of agostic zirconium and hafnium alkyl complexes, (2) the mechanisms of insertion and beta-H elimination reactions of cationic complexes with emphasis on ligand structure/reactivity relationships, (3) catalytically productive ligand C-H activation/C-C coupling reactions including stereoselective reactions with chiral catalysts, and (4) the synthesis and chemistry of new electrophilic metal alkyl catalysts incorporating carborane ligands. These studies will provide new insights into the mechanisms of Ziegler-Natta catalysis, new types of C-H activation chemistry and asymmetric catalysis, and new classes of electrophilic metal alkyl complexes for mechanistic studies and synthetic applications.
