Book excerpt: Oxidative catalysis by metalloporphyrin systems occupies a prominent role in the current research in the fields of chemical and biological catalysis. Our particular interest and approach has been to collect in the same volume papers dealing with both the chemical and biological aspects of the reactivity of heme systems because of the realization that a better understanding of the complementary discipline can be extremely useful for the researchers from either field. The current progress of the research on synthetic metalloporphyrin catalysts has led to the development of several systems that are able to reproduce the heme-enzyme mediated oxygenation and oxidation reactions, at least in terms of reaction types, mechanisms and often rates. These achievements have stimulated the of creating metalloporphyrin catalysts which are both ambitious project efficient and stable enough to become competitive for large-scale industrial processes. Although this project is still far from being realized, the efforts in this direction parallel those aimed at the application of heme enzymes to chemical technologies, e. g. for the mild, selective oxidation of organics or the detoxification of pollutants. Both the two approaches will be advantageous because while the enzyme systems can achieve selectivities which are probably unattainable by synthetic catalysts, the latter can be active under experimental conditions that would readily inactivate the enzymes.

Available in PDF, EPUB and Kindle. Book excerpt: In the ten years that have elapsed since the first edition of this book went to press, the cytochrome P450 field has completed the transition to a discipline in which structure and mechanism, even regulation and biological function, are dealt with in molecular terms. The twin forces that have propelled this remarkable progress have been the widespread adoption of molecular biological approaches and the successful application of modem structural techniques. Only a few P450 primary sequences were available in 1985, whereas hundreds of P450 sequences are now available. Site-specific mutagenesis was then mostly a proverbial gleam in the eye of the P450 community, but it is now a standard technique in the research repertoire. The first crystal structure of a cytochrome P450 enzyme had just been solved in 1985 and appeared on the cover of the first edition. Today, the high-reso lution crystal structures of four soluble bacterial P450 enzymes are available and the race is on to develop approaches that will permit us to determine the structures of the membrane-bound forms of the enzyme. The past ten years has seen phenomenal progress let us hope that the next ten will prove equally exciting. The book is informally divided into four sections. In order to hold the book close to the advancing front of research, some of the chapter topics from the first edition have been dropped to make room for new or expanded topics.

This book was released on 2020-03-23 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is indexed in Chemical Abstracts Service'The present book displays the continuing broad interest in the area of Supramolecular Catalysis. It provides an excellent update to previous contributions in the field and will be highly beneficial reading for all students and researchers interested in the challenges faced in this domain of Supramolecular Chemistry.'Jean-Marie LehnNobel Laureate The construction of catalysts by supramolecular forces has recently become a powerful tool and the role of noncovalent interactions can assist in designing new tools for the construction of effective and selective catalytic systems. It is unquestionably, vastly important to understand how different noncovalent interactions can be controlled or manipulated under appropriate reaction conditions. Supramolecular catalysts have had a tremendous impact on the syntheses of both chemical commodities and fine chemicals over the last 50 years, leading to the discovery of new reactions that were previously deemed impossible. This means that supramolecular chemistry plays a predominant role in accelerating or understanding chemical reactions.This book which addresses the above points is written by some of the leading contributors in this field and is intended for graduate students, researchers and academics working in supramolecular chemistry, organic chemistry, inorganic chemistry, and physical chemistry as well as researchers with an interest in the area of catalysis. The authors give examples illustrating the growth of the field, especially with special emphasis on new results published over the last decade. They also provide an explanation of fundamentals and topical research.

Book excerpt: The Porphyrin Handbook, Volume 19: Applications of Phthalocyanines provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the basic photobiology of phthalocyanines, their structure-activity relationships, mechanisms of action in a variety of biological systems, and their potential applications for various medical purposes. This text then examines the type of organization of the molecules in the solid state and the intensity of the intermolecular interactions. Other chapters consider the applications of phthalocyanines as decorative and functional materials, with emphasis on properties and structures of phthalocyanines with industrial relevance. This book discusses as well the enzyme-like catalytic functions of metal complexes derivatives and their practical applications as odor-removing systems and bacterial systems based on their effective catalytic activities. This book is a valuable resource for research scientists, engineers, and clinicians.

The second meeting was organized as a NATO workshop in Padova, Italy, June 24-27, 1984. This was followed by a meeting in Tsukuba, Japan, July 12-16, 1987. The fourth symposium was held at Balatonfured, Hungary, September 10-14, 1990. The sixth meeting is scheduled to take place in Delft, The Netherlands (late Spring, 1996); the organizer and host will be Professor R. A. Sheldon.

Download or read book Catalytic Oxidations with Hydrogen Peroxide as Oxidant written by G. Strukul and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen peroxide is a chemical that is becoming increasingly fashionable as an oxidant, both in industry and in academia and whose production is expected to increase significantly in the next few years. This growth in interest is largely due to environmental considerations related to the clean nature of hydrogen peroxide as an oxidant, its by-product being only water. To date this chemical has largely been employed as a non-selective oxidant in operations like the bleaching of paper, cellulose and textiles, or in the formulation of detergents, and only to a minimal extent in the manufacture of organic chemicals. This book has been organized to cover the different aspects of the chemistry of hydrogen peroxide. The various chapters into which the book is divided have been written critically by the authors with the general aim of stimulating new ideas and emphasizing those aspects that are likely to lead to new developments in organic synthesis in the coming future.

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.
