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.

This book was released on 2013 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed valency in a ligand bridged homo-polynuclear complex arises when metal centers exist in their different oxidation states. The extent of intermetallic electronic coupling in the mixed valent state of polynuclear complex varies primarily depending on the nature of bridging and ancillary ligands as well as on the metal ion. On the other hand, the use of redox active (redox non-innocent) ligands in the complex framework creates ambiguities in the assignment of valence and spin configurations of such complexes as both the metal and ligand centers can take part in electron transfer processes. In consequence precise determination of valence and spin distributions in transition metal complexes comprising of redox non-innocent ligands is considered to be a formidable challenge. Thus, this book has been focused on how to overcome such problems through the correlation of experimental and theoretical results.

This book was released on 2011 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT continued: These transfer hydrogenation studies are among the first catalytic studies of silyl-pincer complexes and establish [R-PSiP]M species as viable candidates for catalysis. The synthesis and reactivity of 4- and 5-coordinate RuII complexes featuring the [Cy-PSiP] ligand were explored. Reaction of [Cy-PSiP]H with [(p-cymene)RuCl2]2 in the presence of NEt3 and PCy3 resulted in the formation of ([Cy-PSiP]RuCl)2, which serves as a precursor to a series of unprecedented 4-coordinate, formally 14-electron [Cy-PSiP]RuX (X = NHAr, N(SiMe3)2, OtBu) complexes that feature an unusual trigonal pyramidal geometry at Ru. The reactivity of these novel diamagnetic complexes is described, including the reaction of [Cy-PSiP]RuOtBu with amine-boranes resulting in the formation of rare bis(?-BH) complexes. Computational studies confirmed the key role of the strongly ?-donating silyl group of the Cy-PSiP ligand in facilitating the synthesis of such low-coordinate Ru species and enforcing the unusual trigonal pyramidal geometry. The mechanism of ammonia-borane activation was also examined computationally. Lastly, the synthesis and structural characterization of PdII complexes supported by the pincer-like bis(amino)phosphido ligand [?3-(2-Me2NC6H4)2P]- ([NPN]) is described. Examples of ?1-, ?2-, and ?3-NPN coordination to Pd are described, as is the catalytic activity of ([NPN]PdX)2 (X = Cl, OAc, OTf) complexes in the Heck olefin arylation reaction. In an effort to discourage the formation of phosphido-bridged dinuclear complexes, pre-coordination of the Lewis acid BPh3 to [NPN] was pursued. Upon reaction of [N(P?BPh3)N]K with [PdCl(C3H5)]2, the ?1-allyl complex [?3-N(P?BPh3)N]Pd(?1-C3H5) was isolated, which establishes the coordination of a Lewis acid to the phosphido donor of the [NPN] ligand as a viable strategy for encouraging the formation of mononuclear ?3-NPN complexes.

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: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
