Download or read book Applied Cross Coupling Reactions written by Yasushi Nishihara and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Applied Cross-Coupling Reactions” provides students and teachers of advanced organic chemistry with an overview of the history, mechanisms and applications of cross-coupling reactions. Since the discovery of the transition-metal-catalyzed cross-coupling reactions in 1972, numerous synthetic uses and industrial applications have been developed. The mechanistic studies of the cross-coupling reactions have disclosed that three fundamental reactions: oxidative addition, transmetalation, and reductive elimination, are involved in a catalytic cycle. Cross-coupling reactions have allowed us to produce a variety of compounds for industrial purposes, such as natural products, pharmaceuticals, liquid crystals and conjugate polymers for use in electronic devices. Indeed, the Nobel Prize for Chemistry in 2010 was awarded for work on cross-coupling reactions. In this book, the recent trends in cross-coupling reactions are also introduced from the point of view of synthesis design and catalytic activities of transition-metal catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: In this Special Issue, recent advances in cross-coupling reactions are presented in the form of original research articles, reviews, and short communications. These contributions cover different topics in this area, including novel coupling reactions, reaction conditions, synthetic alternatives, metal ligands, and applications for new pharmaceutical compounds and organic materials. In particular, the reviews deal with methodologies such as the synthesis of diarylketones through palladium catalysis and the most relevant examples of Suzuki–Miyaura and Buchwald–Hartwig coupling reactions in the synthesis of bioactive compounds. The synthetic utility of cross-coupling reactions for the synthesis of medium-size rings and the utility of Stille and Suzuki coupling reactions for the synthesis of new molecular machines based on sterically hindered anthracenyl trypticenyl units are also summarized. The original research articles present the synthesis of 2-alkynylpyrrols by inverse Sonogashira coupling and the synthesis of indoles under oxidative dearomative cross-dehydrogenative conditions. The efficient combination of iridium-catalyzed C–H borylation of aryl halides with the Sonogashira coupling and a sequential iridium-catalyzed borylation of NH-free pyrroles followed by a Suzuki–Miyaura reaction are included. The synthesis of aryl propionic acids, a common structural motif in medicinal chemistry, and the synthesis of new organic dyes are also covered.

Book excerpt: Advances in Aggregation Induced Emission Materials in Biosensing and Imaging for Biomedical Applications - Part A Volume 184, highlights many aspects of AIE materials that can help future investigators, researchers, students and stakeholders perform research with ease. Emitting light is a fascinating photophysical phenomenon, its different forms have brought the attention of various disciplines of natural sciences for centuries. In the modern era of scientific generation, short-lived fluorescence light and its long-lived counterpart phosphorescence light has been employed for several chemo-sensing, bio-sensing, and bioimaging applications. The aggregation induced emission (AIE) phenomenon has appeared as a wand of modern science to convert aggregation-caused quenching (ACQ) materials into AIE active materials for a wide range of biomedical applications including biosensing, bioimaging and localization of molecules for better understanding of molecular mechanisms. This volume covers a wide range of topics which are not currently available in a single volume, including ACQ & AIE concept development; intracellular pH, temperature and viscosity sensing; imaging of cell membrane, lipid droplet, lysosome, and mitochondria; biosensing and Imaging of bacteria; nucleus and nucleic acid imaging.

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).

This book was released on 2004-06-15 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of efficient syntheses of medicinal agents is one of the prime goals of the process chemist in the pharmaceutical industry. The expanding list of metal-mediated reactions has had a major impact on this endeavor over the last two decades. This volume will highlight some of the areas of organometallic chemistry that have played a particularly important role in development. The chapters are written by chemists who work in the process groups of major pharmaceutical companies and fine chemical manufacturers. Having demonstrated the power of organometallics in their processes the authors herein expand upon their experiences with examples from the literature as reported by process groups within the industry. The chapters are organized either by the application of a particular metal or reaction class. Removal of the residual metal(s) from the isolated active pharmaceutical ingredient (API) is key to the release of the material for human consumption, and hence, is reviewed here as well. This volume of Topics in Organometallic Chemistry is presented to offer a representative cross section of organometallic applications in the pharmaceutical industry as well as to give an appreciation for the creativity possible in process chemistry.
