This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph consists of manuscripts, summary statements, and poster abstracts submitted by invited speakers and poster contributors who participated in the symposium "Oxygen Complexes and Oxygen Activation by Transition Metals," held March 23-26, 1987, at Texas A&M University. This meeting was the fifth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The co chairmen of the conference were Professors Arthur E. Martell and Donald T. Sawyer of the Texas A&M University Chemistry Department. The program was developed by an academic-industrial steering committee consisting of the co-chairmen and members appointed by the sponsoring chemical companies Dr. James F. Bradzil, The Standard Oil Company, Ohio; Dr. Jerry R. Ebner, Monsanto Company; Dr. Craig Murchison, Dow Chemical Company; Dr. Donald C. Olsen, Shell Development Company; Dr. Tim R. Ryan, Celanese Chemical Company; and Dr. Ron Sanderson, Texaco Chemical Company. The subject of this conference reflects the intense interest that has developed in academic institutions and industry on several aspects of dioxygen chemistry. These include the formation of dioxygen complexes and their applications in facilitated transport and oxygen separation; homo geneous and heterogeneous catalysis of oxidation; and oxygenation of organic substrates by molecular oxygen. The conference differs in two respects from several other symposia on dioxygen chemistry held during the past few years. First, there is extensive industrial participation, especially with respect to oxygen activation.

Book Synopsis Catalytic Activation of Dioxygen by Metal Complexes by : László I. Simándi
Download or read book Catalytic Activation of Dioxygen by Metal Complexes written by László I. Simándi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: The activation of dioxygen by metal ions has both synthetic potential and biological relevance. Dioxygen is the cleanest oxidant for use in emission-free technologies to minimize pollution of the environment. The book gives a survey of those catalyst systems based on metal complexes which have been discovered and studied in the last decade. They activate molecular oxygen and effect the oxidation of various organic compounds under mild conditions. Much of the recent progress is due to a search for biomimetic catalysts that would duplicate the action of metalloenzymes. Mechanistic aspects are emphasized throughout the book. An introductonary chapter reviews the chemistry of transition metal dioxygen complexes, which are usually the active intermediates in the catalytic reactions discussed. Separate chapters are devoted to oxidation of saturated, unsaturated and aromatic hydrocarbons, phenols, catechols, oxo-compounds, phosphorus, sulfur and nitrogen compounds.

This book was released on 2006-04-11 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of dioxygen activation and homogeneous catalytic oxidation by metal complexes has been in the focus of attention over the last 20 years. The widespread interest is illustrated by its recurring presence among the sessions and subject areas of important international conferences on various aspects of bioinorganic and coordination chemistry as well as catalysis. The most prominent examples are ICCC, ICBIC, EUROBIC, ISHC, and of course the ADHOC series of meetings focusing on the subject itself. Similarly, the number of original and review papers devoted to various aspects of dioxygen activation are on the rise. This trend is due obviously to the relevance of catalytic oxidation to biological processes such as dioxygen transport, and the action of oxygenase and oxidase enzymes related to metabolism. The structural and functional modeling of metalloenzymes, particularly of those containing iron and copper, by means of low-molecular complexes of iron, copper, ruthenium, cobalt, manganese, etc., have provided a wealth of indirect information helping to understand how the active centers of metalloenzymes may operate. The knowledge gained from the study of metalloenzyme models is also applicable in the design of transition metal complexes as catalytsts for specific reactions. This approach has come to be known as biomimetic or bioinspired catalysis and continues to be a fruitful and expanding area of research.

Download or read book Metal Complex Faciliated Transport and Activation of Molecular Oxygen written by Kenneth John Balkus and published by . This book was released on 1986 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research reported in Chapters I-IV involves the synthesis and spectroscopic characterization of synthetic 2 and CO carriers, improvement of the stability and reversibility of these metal dioxygen and carbonyl complexes by varying the supports and ligand environment, and the incorporation of these complexes in polystyrene membranes as part of a novel gas separation process. Bi s (salicylidene-Y-iminopropyl) methylaminoco bait (II) and derivations thereof, supported on both polystyrene and silica which bind O2 reversibly in the solid state, are described in detail. The characterization of a novel zeolite encapsulated anionic complex is also reported. This compound, proposed to be Co(CN)Y, binds dioxygen reversibly, at least 400 cycles and is stable to moisture. Several new Cu(ll) complexes supported on polystyrene were prepared and their reversible interaction with carbon monoxide was investigated. A new method for the separation of oxygen from air is presented. The system involves the incorporation of supported transition metal complexes that reversibly bind dioxygen into polystyrene membranes in order to facilitate the transport of O2. These films, subsequently employed in a closed volume experiment, exhibited enhanced 2 permselectivity . The permeation apparatus, experimental procedure and membrane characterization are presented in detail. A mechanism of transport which involves a site to site interaction between metal centers is discussed. The work in Chapter V focuses on employing lacunary heteropolyanions (HPAs) as oxidatively resistant ligands for catalytically active metal ions. The reactivity in organic solvents of CXMW 1 ^39"", where M = Co(II), Mn(ll) and Fe(III), was investigated. In the presence of alkyl peroxide or iodosylbenzene, these HPAs were found to catalyze the oxidation of several organic substrates. This research led to the discovery of a dirhodium heteropolytungstate catalyst. This polyoxometallate is proposed to be a metal-metal bonded Rh 2 substituted Keggin ion. The preparation and characterization of this compound are described in detail. The RhHPA was found to be an effective catalyst for the allylic oxidation of cyclic olefins by molecular On. Unusual selectivity for the production of the a, g- unsaturated carbonyl was observed. A consideration of the general features of this reaction led to a proposed mechanism which involves an ion free radical decomposition of insitu generated peroxides.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen activation and binding to two transition-metal systems: late transition-metal system Pd(L1)(L2) (L1= NHC, L2= NHC or PR3) and early transition-metal system V(N(tBu)Ar)3 (Ar = 3,5-Me2C6H3) was explored in order to gain information about the thermodynamics, kinetics and mechanism of O2 binding to metal complexes. In this work, a novel oxygen binding mode was discovered and the resulting complex Pd(IPr)2([eta]1-O2)2 was reported as the first [eta]1 oxygenation palladium complex. This reaction was further studied and a plausible mechanism of O2 binding to Pd(L1)(L2) system was proposed, in which the effect of ligands bulkiness and an equilibrium between [eta]1-Pd and [eta]2-Pd were highlighted. In addition, an early transition-metal peroxo complex V(N(tBu)Ar)3([eta]2-O2) has been prepared directly by reaction with O2. Its equilibrium with V(N(tBu)Ar)3([eta]1-O2) and its reactivity were investigated. Finally the binding and activation of a potent oxygen atom transfer reagent MesCNO were studied.

This book was released on 2003-10-14 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book distils the research accomplishments of Professor Fred Basolo during the five decades when he served as a world leader in the modern renaissance of inorganic chemistry. Its primary focus is on the very important area of chemistry known as coordination chemistry.Most of the elements in the periodic table are metals, and most of the chemistry of metals involves coordination chemistry. This is the case in the currently significant areas of research, including organometallic homogenous catalysis, biological reactions of metalloproteins, and even the solid state extended structures of new materials. In these systems, the metals are of primary importance because they are the sites of ligand substitution or redox reactions. In the solid materials, the coordination number of the metal and its stereochemistry are of major importance.Some fifty years of research on transition metal complexes carried out in the laboratory of Professor Basolo at Northwestern University is recorded here as selected scientific publications. The book is divided into three different major research areas, each dealing with some aspect of coordination chemistry. In each case, introductory remarks are presented which indicate what prompted the research projects and what the major accomplishments were. Although the research was of the academic, curiosity-driven type, some aspects have proven to be useful to others involved in projects that were much more applied in nature.

This book was released on 2006-04-11 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known to be the less reactive organic compounds. Saturated hydrocarbons may be called the “noble gases of organic chemistry” and, if so, the first representative of their family – methane – may be compared with extremely inert helium. As in all comparisons, this parallel between noble gases and alkanes is not fully accurate. Indeed the transformations of alkanes, including methane, have been known for a long time. These reactions involve the interaction with molecular oxygen from air (burning – the main source of energy!), as well as some mutual interconversions of saturated and unsaturated hydrocarbons. However, all these transformations occur at elevated temperatures (higher than 300–500 °C) and are usually characterized by a lack of selectivity. The conversion of alkanes into carbon dioxide and water during burning is an extremely valuable process – but not from a chemist viewpoint.
