Mechanisms of Chemical Reactions Involved in Catalysis by Organometallic Complexes in Solution

这个无机、生物无机和有机金属化学项目的奖项为科罗拉多州立大学化学系的杰克·r·诺顿博士对过渡金属氢化物键的酸度和强度的研究提供了持续的支持。具体项目包括确定双核配合物酸化反应中的中间体；测定各种过渡金属氢化物的相对给氢能力；确定二氮和相关配体的质子化位置；研究了锆新世烷基配体的酸裂解机理和钯催化芳基碘化物与有机锡的偶联反应。过渡金属氢化物配合物是许多催化过程中重要的中间体，如烯烃的加氢和聚合以及氢甲酰化反应。虽然这些研究是基础性的，但它们有望为理解催化活性提供重要的信息。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry program provides continued support to Dr. Jack R. Norton of the Chemistry Department, Colorado State University, for research on the acidity and strength of transition metal hydride bonds. Specific projects include identifying the intermediate in acidification reactions of binuclear complexes; determining the relative hydride donor abilities of various transition metal hydrides; determining the site of protonation of dinitrogen and related ligands; and investigating the mechanism of acid cleavage of alkyl ligands from zirconocene and of the palladium-catalyzed coupling of aryl iodides with organotin. %%% Transition metal hydride complexes are important intermediates in many catalytic processes, such as the hydrogenation and polymerization of olefins and hydroformylation reactions. Although these studies are fundamental, they are expected to provide information important to understanding catalytic activity.
