Reactivity of Complexes Containing the Nitrosyl(pentamethyl-cyclopentadienyl)ruthenium Core

该项目由无机、生物无机和有机金属化学项目资助，重点研究含有钌-五甲基环戊二烯基亚硝基部分的配合物的化学几个方面。具体目标包括：1)研究烷基-氯甲基配合物中碳-碳键的形成；2)烷基配合物阳离子的生成（通过二烷基前体的质子化）以及它们与亲核试剂（如水、胺、炔、烯烃和CO）的反应。钌五甲基环戊二烯基亚硝基的生成及其与亲核试剂反应的研究。从这些研究中获得的信息有望深入了解C-C和C-E （E = N， O）键的形成，α和β迁移插入和消除过程，C-H键的氧化添加/还原消除以及醇的催化氧化。这个项目涉及研究一类有机钌化合物的基本反应性。这项工作的结果预计将影响几种具有重要技术意义的催化反应。

This project, funded by the Inorganic, Bioinorganic and Organometallic Chemistry Program, focusses on several aspects of the chemistry of complexes that contain the ruthenium- pentamethylcyclopentadienylnitrosyl moiety. Specific objectives include 1) the investigation of carbon-carbon bond formation in alkyl-chloromethyl complexes, 2) generation of alkyl complex cations (by protonation of dialkyl precursors) and the study of their reactions with nucleophiles such as water, amines, alkynes, olefins and CO, 3) generation of the rutheniumpentamethylcyclopentadienylnitrosyl dication and examination of its reactions with nucleophiles. The information obtained from these studies are expected to provide insight into C-C and C-E (E = N, O) bond formation, alpha and beta migratory insertion and elimination processes, oxidative addition/reductive elimination of C-H bonds, and catalytic oxidation of alcohols. %%% This project involves the study of the fundamental reactivity properties of a class of organoruthenium compounds. The results of this work are expected to impact several types of catalytic reactions of significant technological importance.
