Book Synopsis Synthesis and Characterization of Metal-Metal Multiply Bonded Complexes and Catalytic Applications of Solvent Stabilized Transition Metal Complexes for Polymerization of Olefins by :
Download or read book Synthesis and Characterization of Metal-Metal Multiply Bonded Complexes and Catalytic Applications of Solvent Stabilized Transition Metal Complexes for Polymerization of Olefins written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of dimolybdenum quadruply bonded complexes and dirhodium compounds were synthesized and characterized. Additionally a variety of solvent stabilized transition metal complexes were explored as initiators for the polymerization of olefins. The polymerization of cyclopentadiene and methylcyclopentadiene was employed as standard reaction. The results revealed that the metal-metal bond plays no important role in the activity of the examined bimetallic complexes and that the mononuclear complexes show excellent activity, which is in good correlation to their predicted ligand field stabilization energy as a function of the number of d electrons available. Furthermore, the analyses of the MCM-41-supported dimolybdenum species indicated that the quadruple bond is retained and their activity is held in the heterogenization process.

Book Synopsis Synthesis, Characterization And Catalytic Activity Of Ba(II) Complexes by : Rohit Patel
Download or read book Synthesis, Characterization And Catalytic Activity Of Ba(II) Complexes written by Rohit Patel and published by LAP Lambert Academic Publishing. This book was released on 2015-10-25 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to explain the formulae and structures of the complex compounds or complexes, formed by transition metal salts with molecular species such as ammonia, Werner coined the terms primary valence and secondary valence.. These concepts remain valid today except that the term oxidation state has replaced 'primary valence' and the term coordination number has replaced 'secondary valence' Werner had recognized that a transition metal salt could form a complex compound in which the metal ion became bonded to a number of groups which need not necessarily be the counter anions originally present in the salt. The orientations in space of these metal-bond groups would lead to the complex having a particular geometric structure. Coordination compound has always been a challenge to the inorganic chemistry. The scientists of coordination of compound are Kooser, Lewis, Sidgwick, etc.

Book Synopsis Mechanochemical Organic Synthesis by : Davor Margetic
Download or read book Mechanochemical Organic Synthesis written by Davor Margetic and published by Elsevier. This book was released on 2016-04-23 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions Integrates advances in green chemistry research into industrial applications and process development Focuses on designing techniques in organic synthesis directed toward mild reaction conditions Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds
Book Synopsis Aqueous Organometallic Catalysis by : Ferenc Joo
Download or read book Aqueous Organometallic Catalysis written by Ferenc Joo and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 20 years aqueous organometallic catalysis has found applications in small- scale organic synthesis in the laboratory, as well as in the industrial production of chemicals with a combined output close to one million tons per year. Aqueous/organic two-phase reactions allow easy product-catalyst separation and full catalyst recovery which mean clear benefits not only in economic but also in environmental and green chemistry contexts. Instead of putting together a series of expert reviews of specialized fields, this book attempts to give a comprehensive yet comprehensible description of the various catalytic transformations in aqueous systems as seen by an author who has been working on aqueous organometallic catalysis since its origin. Emphasis is put on the discussion of differences between related non-aqueous and aqueous processes due to the presence of water. The book will be of interest to experts and students working in catalysis, inorganic chemistry or organic synthesis, and may serve as a basis for advanced courses.

Book Synopsis Biocatalysis Based on Heme Peroxidases by : Eduardo Torres
Download or read book Biocatalysis Based on Heme Peroxidases written by Eduardo Torres and published by Springer Science & Business Media. This book was released on 2010-08-20 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last systematic description of heme peroxidases was published in 1999 by Brian Dunford, from the University of Alberta in Canada. The book Heme per- idases covers discussion on three-dimensional structure, reaction mechanism, kinetics, and spectral properties of representative enzymes from bacterial, plant, fungal, and animal origin. Since 1999, vast information on basic but also applied aspects of heme peroxidases has been generated. We believe fusion of these two aspects will bene?t research of those dedicated to development of biocatalytic process. The aim of this book is to present recent advances on basic aspects such as evolution, structure–function relation, and catalytic mechanism, as well as applied aspects, such as bioreactor and protein engineering, in order to provide the tools for rational design of enhanced biocatalysts and biocatalytic processes. The book does not include an exhaustive listing of references but rather a selected collection to enrich discussion and to allow envisioning future directions for research. This book is organized in three parts. In Part I, current knowledge of structure and mechanism of peroxidases is covered. From the molecular phylogeny, going through the in?uence of structural factors over oxidative ability to the molecular mechanism of catalysis, the authors intend to provide an understanding of per- idases at the molecular level. The understanding of the fundamental behavior of peroxidases will allow further adequation, design, and/or optimization of pero- dase-based catalysis to a particular process. In Part II, research on potential applications of peroxidases in several ?elds is presented and discussed.
Book Synopsis Periodic Mesoporous Organosilicas by : Chang-Sik Ha
Download or read book Periodic Mesoporous Organosilicas written by Chang-Sik Ha and published by Springer. This book was released on 2018-11-07 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material. The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.
Download or read book Chemistry of Iron written by J. Silver and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to be of use to the reader in two different ways. First, it is intended to provide a general introduction to all aspects of iron chemistry for readers from a variety of different scientific backgrounds. It has been written at a level suitable for use by graduates and advanced undergraduates in chemistry and biochemistry, and graduates in physics, geology, materials science, metallurgy and biology. It is not designed to be a dictionary of iron compounds but rather to provide each user with the necessary tools and background to pursue their ,individual interests in the wide areas that are influenced by the chemistry of iron. To achieve this goal each chapter has been written by a contemporary expert active in the subject so that the reader will benefit from their individual insight. Although it is generally assumed that the reader will have an understanding of bonding theories and general chemistry, the book is well referenced so that any deficiencies in the reader's background can be addressed. The book was also designed as a general reference book for initial pointers into a scientific literature that is growing steadily as the understanding and uses of this astonishingly versatile element continue to develop. To meet this aim the book attempts some coverage of all aspects of the chemistry of iron, not only outlining what understanding has been achieved to date but also identifying targets to be aimed at in the future.
