Available in PDF, EPUB and Kindle. Book excerpt: It is now IS years since the first patents in polymer supported metal complex catalysts were taken out. In the early days ion-exchange resins were used to support ionic metal complexes. Soon covalent links were developed, and after an initially slow start there was a period of explosive growth in the mid to late 1970s during which virtually every homogeneous metal complex catalyst ever reported was also studied bound to a support. Both polymers and inorganic oxides were studied as supports, although the great preponderance of workers studied polymeric supports, and of these polystyrene was by far the commonest used. This period served to show that by very careful design polymer-supported metal complex catalysts could have specific advantages over homogeneous metal complex catalysts. However the subject was a complicated one. Merely immobilising a successful metal complex catalyst to a functionalised support rarely yielded other than an inferior version of the catalyst. Amongst the many discouraging results of the 1970s, there were more than enough results that were sufficiently encouraging to demonstrate that, by careful design, supported metal complex catalysts could be prepared in which both the metal complex and the support combined together to produce an active catalyst which, due to the combination of support and complex, had advantages of activity, selectivity and specificity not found in homogeneous catalysts. Thus a new generation of catalysts was being developed.

Download or read book Catalysis by Metal Complexes and Nanomaterials written by Meng Zhou (Chemistry professor) and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Catalysis is truly an interdisciplinary field to which chemists, biologists, physicists, and engineers have made seminal contributions. This book aims to address the notably diverse topic of transition-metal catalysis in a single volume. The first half of the book is dedicated to the discrete and atomically precise metal complexes for homogeneous catalysis. Bimetallic, organometallic, and coordination complexes of early, late, and post-transition metals are described. Catalytic hydrogenation, oxidation, and coupling reactions are presented. The second half of the book focuses on three distinct types of nanomaterials: (1) zero- valent metallic nanoparticles, (2) titanium dioxide semiconductors, and (3) the porous coordination polymer known as the metal-organic framework. The chapters illustrate how deeply catalysis is influenced by other disciplines (e.g., coordination chemistry, bioinorganic chemistry, organometallic chemistry, computational chemistry, organic synthesis, photochemistry, materials science, environmental chemistry, green chemistry, and renewable energy). Advancements in these areas fuel the rapid growth of catalysis science. This book allows readers to reach a high-level of understanding in catalysis by learning from the perspectives of active practitioners. Unlike a textbook that provides a systematic, comprehensive, and historical education on the general topics of catalysis, this book offers critical case studies on select topics. Substantial emphasis is placed on the structural and fundamental properties that dictate catalyst performance, enabling readers to quickly understand and apply knowledge from cutting-edge studies and applications detailed within. This book can be utilized as a handbook, a textbook or textbook supplement, or a reference to guide future work"--

Download or read book Advances in Catalytic Activation of Dioxygen by Metal Complexes written by László I. Simándi and published by Springer Science & Business Media. 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 Complexes in Aqueous Solutions written by Arthur E. Martell and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability constants are fundamental to understanding the behavior of metal ions in aqueous solution. Such understanding is important in a wide variety of areas, such as metal ions in biology, biomedical applications, metal ions in the environment, extraction metallurgy, food chemistry, and metal ions in many industrial processes. In spite of this importance, it appears that many inorganic chemists have lost an appreciation for the importance of stability constants, and the thermodynamic aspects of complex formation, with attention focused over the last thirty years on newer areas, such as organometallic chemistry. This book is an attempt to show the richness of chemistry that can be revealed by stability constants, when measured as part of an overall strategy aimed at understanding the complexing properties of a particular ligand or metal ion. Thus, for example, there are numerous crystal structures of the Li+ ion with crown ethers. What do these indicate to us about the chemistry of Li+ with crown ethers? In fact, most of these crystal structures are in a sense misleading, in that the Li+ ion forms no complexes, or at best very weak complexes, with familiar crown ethers such as l2-crown-4, in any known solvent. Thus, without the stability constants, our understanding of the chemistry of a metal ion with any particular ligand must be regarded as incomplete. In this book we attempt to show how stability constants can reveal factors in ligand design which could not readily be deduced from any other physical technique.

Other topics covered are the quantitative data on the comparison of catalyses by mobile and immobilized metal complexes; main factors affecting the activity of these catalytic systems and methods of optimizing their control; and specific problems of catalysis by fixed complexes (e.g., ligand exchange and electron transfer in metal polymer systems, macromolecular effects and polyfunctional catalysis).

Download or read book Metal Complexes written by Peter Maitlis and published by Elsevier. This book was released on 2012-12-02 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Organic Chemistry of Palladium, Volume 1: Metal Complexes deals with the number of organic reactions that can be catalyzed by palladium, particularly as regards the structures bonding, and reactions of the metal complexes. The book discusses monodentate ligands which are either neutral (carbonyls, isonitriles, carbenes) or anionic (methyl, phenyl, ethynyl, hydride). The text also examines the complexes formed by 1,3-. 1,4-, and 1,5-diolefins where four carbon atoms are bound to the metal. Palladium (II) can undergo a reaction with the 1,3-dienes and results in a ?-allylic complexes where only three carbon atoms are coordinated to the metal. (The bonding situation in complexes 1,4- and 1,5-dienes, where no great interaction between the olefins are similar to that in monoolefin complexes, is straightforward), Olefins can also react with palladium chloride in protic solvents to produce ketones (or aldehydes) or organic coupling products. Some experiments conducted by Huttel et al shows that some palladium was precipitated from the reactions giving lower yields, resulting in various aldehydes and ketones as by products. The book also discusses cyclopentadienyl and benzene complexes. The text can prove beneficial for researchers, investigators and scientists whose works involve organic chemistry, analytical chemistry, physical chemistry and inorganic chemistry.
