Available in PDF, EPUB and Kindle. Book excerpt: Ruthenium Oxidation Complexes explores ruthenium complexes, particularly those in higher oxidation states, which function as useful and selective organic oxidation catalysts. Particular emphasis is placed on those systems which are of industrial significance. The preparation, properties and applications of the ruthenium complexes are described, followed by a presentation of their oxidative properties and summary of the different mechanisms involved in the organic oxidations (e.g. oxidations of alcohols, alkenes, arenes and alkynes, alkanes, amines, ethers, phopshines and miscellaneous substrates). Moreover, future trends and developments in the area are discussed. This monograph is aimed at inorganic, organic, industrial and catalysis chemists, especially those who wish to carry out specific organic oxidations using catalytic methods.

This book was released on 2012 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research covered in this thesis involves studying and understanding the behavior of bifunctional ligands, specifically imidazolylphoshines. The major field of study is reaction of cyclopentadienyl ruthenium complexes with olefins, namely alkene isomerization. In these complexes, the basic nitrogen of the imidazolylphosphine is thought to deprotonate coordinated alkene intermediates reversibly, facilitating isomerization of terminal alkenes to yield internal alkenes selectively. The CpRu alkene isomerization catalyst is capable of moving double bonds as far as 30 positions; further mechanistic studies in presence of deuterium labeling as a tool, has led to development of hydrogen deuterium exchange of olefins at allylic positions. This finding supports the proposed mechanism and provides and outstanding deuteration at positions accessible by isomerization. The alkene isomerization catalyst can be used in a two-phase setting where the catalyst is dissolved in the organic layer and the non-toxic, non-flammable isotopic source (D2O) is immiscible with the organic layer. Using biphasic settings one can literally wash out reactive protons on the substrate without using organic solvents. In order to control high activity of alkene isomerization catalyst in absence of steric bulk provided by the substrate, bulkier phosphine ligands were synthesized and the activity of their metal complexes toward linear olefins was investigated. As a result, a family of catalysts that is capable of isomerizing unsubstituted linear alkenes to various mixtures have been established, where one can choose a complex to fit the needs of the process at hand. Further investigation with terminal alkenes bearing functional groups can be carried out to investigate whether mono-isomerization will still be the major transformation taking place, which is expected to give access to high-value 2-alkenes. To provide easy product-catalyst separation and potential wider application, the first syntheses of polymer-supported imidazolylphophines were developed, and the alkene isomerization catalyst was thus immobilized on polystyrene-based Merrifield resin. Compared to the homogeneous catalyst, the immobilized catalysts give the same high (E)-selectivity and conversion in isomerizations of terminal olefins to internal olefins with very low metal leaching from the insoluble support. Furthermore, use of organic solvents can be excluded and isomerization can be carried out in neat liquid organic substrates.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the preparation and catalytic reactivity of novel half-sandwich ruthenium complexes supported by N-Heterocyclic Carbene (NHC) ligands. The cationic half-sandwich ruthenium complexes [Cp(IPr)Ru(CH3CN)2]+ show interesting reactivities toward the transfer hydrogenation of different unsaturated substrates, such as ketones, olefins, N-heterocycles, and nitriles. Kinetic studies disclose that a neutral trishydride ruthenium complex is actually involved in the catalytic cycle, playing the role as a resting state. Further investigations on the sub-class of trishydride ruthenium complexes bearing NHC ligands (Cp'(NHC)RuH3) reveal that these complexes have an unusual and great catalytic performance toward the hydrodefluorination (HDF) of fluorinated aromatic and aliphatic compounds. The combined kinetic studies, cross-over experiments and rate law analysis suggest an unusual mechanistic pathway for the Cp*(IPr)RuH3 catalyzed HDF. This study is one of the rare examples where isopropanol is employed as a reducing agent for the metal-mediated HDF reaction. A class of silyl dihydride ruthenium complexes, derived from Cp(IPr)RuH3 are prepared. These silyl hydrido derivatives are great compounds for the study of the inter ligand hypervalent interaction (IHI), an interesting phenomenon for many non-classical silane complexes. This study also suggests that the replacement of phosphines by their isolobally analogous NHC ligands result in stronger IHI interactions in the corresponding compounds. Another type of non-classical interaction was systematically scrutinized in a ii series of new cationic and neutral silane sigma complexes of ruthenium bearing different silyl moieties. These new NHC-supported ruthenium complexes allow for direct comparation with the known phosphine analogues, which reveals interplay of steric and electronic factors on the extent of Si-H complexation to metal and the extent of additional interligand interactions between Ru-Cl and chlorosilane ligand. Finally, new trishydride ruthenium complexes bearing NHC ligands (Cp'(NHC)RuH3) catalyze the H/D exchange reaction of various N-heterocycle substrates; their catalytic performance can be considered as one of the mildest, and most efficient approaches.
