Download or read book Ruthenium Complexes written by Alvin A. Holder and published by John Wiley & Sons. This book was released on 2018-02-27 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edited by a team of highly respected researchers combining their expertise in chemistry, physics, and medicine, this book focuses on the use of rutheniumcontaining complexes in artificial photosynthesis and medicine. Following a brief introduction to the basic coordination chemistry of ruthenium complexes and their synthesis in section one, as well as their photophysical and photochemical properties, the authors discuss in detail the major concepts of artificial photosynthesis and mechanisms of hydrogen production and water oxidation with ruthenium in section two. The third section of the text covers biological properties and important medical applications of ruthenium complexes as therapeutic agents or in diagnostic imaging. Aimed at stimulating research in this active field, this is an invaluable information source for researchers in academia, health research institutes and governmental departments working in the field of organometallic chemistry, green and sustainable chemistry as well as medicine/drug discovery, while equally serving as a useful reference also for scientists in industry.

Book excerpt: This book will describe Ruthenium complexes as chemotherapeutic agent specifically at tumor site. It has been the most challenging task in the area of cancer therapy. Nanoparticles are now emerging as the most effective alternative to traditional chemotherapeutic approach. Nanoparticles have been shown to be useful in this respect. However, in view of organ system complicacies, instead of using nanoparticles as a delivery tool, it will be more appropriate to synthesize a drug of nanoparticle size that can use blood transport mechanism to reach the tumor site and regress cancer. Due to less toxicity and effective bio-distribution, ruthenium (Ru) complexes are of much current interest. Additionally, lumiscent Ru-complexes can be synthesized in nanoparticle size and can be directly traced at tissue level. The book will contain the synthesis, characterization, and applications of various Ruthenium complexes as chemotherapeutic agents. The book will also cover the introduction to chemotherapy, classification of Ru- complexes with respect to their oxidation states and geometry, Ruthenium complexes of nano size: shape and binding- selectivity, binding of ruthenium complexes with DNA, DNA cleavage studies and cytotoxicity. The present book will be more beneficial to researchers, scientists and biomedical. Current book will empower specially to younger generation to create a new world of ruthenium chemistry in material science as well as in medicines. This book will be also beneficial to national/international research laboratories, and academia with interest in the area of coordination chemistry more especially to the Ruthenium compounds and its applications.

Available in PDF, EPUB and Kindle. Book excerpt: Tracing the life of a giant in inorganic chemistry and key trends in his science, Boranes and Beyond follows Hawthorne from his mid-American origins to the halls of Harvard and UCLA and back again. It naturally details the accomplishments in his lab. This book is a fascinating mixture of science and autobiography. Prof. Hawthorne won the Priestley Medal, the highest award of the American Chemical Society, for his pioneering work in elucidating the chemistry of boron. He has chronicled in this book the developments in his lab which ultimately led to this achievement. Not content to rest on his laurels, after retiring from UCLA Prof. Hawthorne explored the use of boron in biomedicine and directed the International Institute of Nano & Molecular Medicine at the University of Missouri-Columbia.

This book was released on 2004 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes three investigations of the dinuclear ruthenium complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4: (1) its use as a catalyst for the hydroamination of alkynes by a new mechanism, (2) its reactions with H2 to give new ruthenium clusters containing bridging hydride ligands, and (3) the determination of thermodynamic and kinetic acidities of two related complexes [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3[P(OR)3]HBF4− (R= Me, Ph). A fundamentally new mechanism for alkyne hydroamination catalyzed by the ruthenium complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3(C2H4)H+BF4−, has been proposed. Many of the intermediates in the catalytic cycle have been isolated and/or characterized spectroscopically and found to react according to the proposed mechanism. The catalyst activity is terminated as a result of the isomerization of a bridging alkyne ligand in a key intermediate in the catalytic cycle. The butterfly cluster, [([eta]5-C5H3)2(SiMe2)2]2Ru4(CO)3H4, and the square planar cluster, [([eta]5-C5H3)2(SiMe2)2]2Ru4(CO)4H4, have been isolated from the photochemical reaction of H2 with the doubly-linked dicyclopentadienyl complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4, in benzene. Wavelength-dependent photolysis studies suggest that the first step in the reaction of [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4 with H2 involves metal-metal bond cleavage. The reaction of the protonated phosphite complexes, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3[P(OR)3]H+BF4− (R= Me, Ph), with tertiary amines (DABCO, 4-methylmorpholine, NEt3, N(n-Bu)3) results in clean deprotonation of the metal-metal bond by the amine. Equilibrium measurements show that the P(OPh)3 complex is more acidic than the P(OMe)3 complex. The rates of deprotonation of the phosphite complexes have been determined and follow the rate law: Rate = k1[complex] + k2[amine][complex]. Comparisons of the k2 rate constants reveal that the reactions are much more sensitive to the steric properties of the amine and metal complex than to electronic factors.

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.
