Download or read book EPR of Free Radicals in Solids II written by Anders Lund and published by Springer Science & Business Media. This book was released on 2012-12-09 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: EPR of Free Radicals in Solids: Trends in Methods and Applications, 2nd ed. presents a critical two volume review of the methods and applications of EPR (ESR) for the study of free radical processes in solids. Emphasis is on the progress made in the developments in EPR technology, in the application of sophisticated matrix isolation techniques and in the advancement in quantitative EPR that have occurred since the 1st edition was published. Improvements have been made also at theoretical level, with the development of methods based on first principles and their application to the calculation of magnetic properties as well as in spectral simulations. EPR of Free Radicals in Solids II focuses on the trends in applications of experimental and theoretical methods to extract structural and dynamical properties of radicals and spin probes in solid matrices by continuous wave (CW) and pulsed techniques in nine chapters written by experts in the field. It examines the studies involving radiation- and photo-induced inorganic and organic radicals in inert matrices, the high-spin molecules and metal-based molecular clusters as well as the radical pro-cesses in photosynthesis. Recent advancements in environmental applications in-cluding measurements by myon resonance of radicals on surfaces and by quantitative EPR in dosimetry are outlined and the applications of optical detection in material research with much increased sensitivity reviewed. The potential use of EPR in quantum computing is considered in a newly written chapter. This new edition is aimed to experimentalists and theoreticians in research involving free radicals, as well as for students of advanced courses in physical chemis-try, chemical physics, materials science, biophysics, biochemistry and related fields.

Download or read book Kinetics and Spectroscopy of Carbenes and Biradicals written by M.S. Platz and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of mechanistic organic chemistry is filled with claims of short-lived reactive intermediates connecting starting material to product. In many ways this book represents a personal odyssey of the editor in this area of chemistry. I well remember my introduction to organic chemistry as an undergraduate working in the laboratories of Shelton Bank at SUNY Albany in the early 1970s, and the excitement and frustration attending the piecing together of the details of a reaction mechanism by working backwards from the stable products of the reaction. In those days the reaction and the reactive intermediates flew by too rapidly to permit direct observation. Thus it came as something of a revelation to me as a graduate student at Yale that it was possible to slow down a reaction and actually "see" such ephemeral species as carbenes and biradicals by spectroscopic methods, by generating them photochemically at cryogenic temperatures. In this monograph several chap ters are devoted to low-temperature studies. Dougherty has described the matrix EPR spectra of biradicals, which were pure conjecture only ten years ago. Michl and Arnold have described the matrix spectroscopy of cyciobutadiene, a molecule that has fascinated organic chemists for over a hundred years. They have shown that by using a combination of matrix spec troscopic methods it is possible to learn nearly as much about the structure of cyciobutadiene, the prototypical antiaromatic biradicaloid, as about that of a common shelf-stable reagent.

Download or read book Cross Coupling Reactions written by Norio Miyaura and published by Springer. This book was released on 2003-07-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1972, a very powerful catalytic cycle for carbon-carbon bond formation was 2 first discovered by the coupling reaction of Grignard reagents at the sp -carbon. Over the past 30 years, the protocol has been substantially improved and expanded to other coupling reactions of Li,B,N,O,Al,Si,P,S,Cu,Mn,Zn,In,Sn, and Hg compounds. These reactions provided an indispensable and simple methodology for preparative organic chemists. Due to the simplicity and rel- bility in the carbon-carbon, carbon-heteroatom, and carbon-metalloid bo- formations,as well as high efficiency of the catalytic process,the reactions have been widely employed by organic chemists in various fields. Application of the protocol ranges from various syntheses of complex natural products to the preparation of biologically relevant molecules including drugs, and of sup- molecules, and to functional materials. The reactions on solid surfaces allow robot synthesis and combinatorial synthesis. Now, many organic chemists do not hesitate to use transition metal complexes for the transformation of org- ic molecules. Indeed, innumerable organic syntheses have been realized by the catalyzed reactions of transition metal complexes that are not achievable by t- ditional synthetic methods. Among these, the metal-catalyzed cross-coupling reactions have undoubtedly contributed greatly to the development of such a new area of “metal-catalyzed organic syntheses”. An excellent monograph for the cross-coupling reactions and other met- catalyzed C-C bond-forming reactions recently appeared in Metal-catalyzed Cross-coupling Reactions (Wiley-VCH,1998).
