Download or read book Nanoparticles in Catalysis written by Shū Kobayashi and published by Springer Nature. This book was released on 2020-11-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses the great potential of metal nanoparticle catalysts for complicated molecular synthesis and reviews the current progress of this field. The development of highly active and stable heterogeneous catalysts is a crucial subject in modern science. However, development of heterogeneous catalysts for fine chemical synthesis has lagged far behind those for bulk chemical process. In recent years metal nanoparticle catalysts have been of great interest in this area due to their unique activity, ease of heterogenization, and robustness. Therefore, metal nanoparticle catalysts are an excellent candidate for the above-mentioned active and robust heterogeneous catalysts and this book provides an overview of this area. The present volume summarizes recent progress on nanoparticle catalysis for various organic transformations from simple redox reactions to complex asymmetric C–C bond forming reactions and also presents seminal studies on new technologies. It comprehensively summarizes advances in metal nanoparticle catalysis across several aspects including reaction manners, mechanistic investigations and new synthetic methodologies to encourage the use of metal nanoparticle catalysts for future organic synthesis. This volume will be of interest to students, researchers and professionals focused on the next-generation of fine chemical synthesis.

Download or read book New Trends in Asymmetric Catalysis written by Giorgio Della Sala and published by MDPI. This book was released on 2021-08-30 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of enantiopure organic compounds is a key issue for several applications in pharmacology, food chemistry, agricultural chemistry, perfumery, materials science and other industrial sectors. Nowadays, asymmetric catalysis is undoubtedly the most important tool to achieve this goal. This technology, in fact, enables the production of large amounts of enantiomerically enriched compounds, employing relatively small quantities of chiral enantiopure catalysts, which is exactly what is accomplished by enzymes in nature. Since the pioneering works of Noyori, Knowles and Sharpless, which later earned them the Nobel Prize in Chemistry, asymmetric catalysis has experienced a rapid and relentless development in the last fifty years. The tremendous expansion of enantioselective transformations, the design of novel and more efficient organometallic and organic catalysts, the development of sophisticated bioreactors and cell factories, are just some of the elements responsible for such growth. However, new challenges of asymmetric catalysis are devoted to enhancing the process’s sustainability, by the introduction of recyclable and low-cost catalysts, and the use of renewable starting materials and energy source. This book provides an overview of some of these development directions and comprises a collection of review papers and a research article authored by renowned researchers actively involved in this field. The topics covered by the review papers are photoredox-catalyzed reactions of imines, asymmetric catalytic electrosynthesis, cooperative catalysis of chiral N-heterocyclic carbenes and Lewis acid, and asymmetric ring-opening reactions of epoxides catalyzed by metal–salen complexes. The research article presents a proline-catalyzed aldol reaction in water–methanol solvent mixture.
Download or read book Advances in Asymmetric Autocatalysis and Related Topics written by Gyula Palyi and published by Academic Press. This book was released on 2017-05-18 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Asymmetric Autocatalysis and Related Topics provides various viewpoints on the important developments in asymmetric autocatalysis that have occurred in the past few years, also including brand new information in the field. Asymmetric autocatalysis is a chemical reaction which leads from achiral starting materials to chiral products, and in which the product accelerates its own formation reaction (conventional catalysis) and promotes the prevalence of its own chiral configuration (asymmetric induction). The combination of these two effects in the same reaction was unprecedented before 1995 when it was first described by Kenso SOAI at the Tokyo University of Science. Since then, several new combinations of this effect have been found, most intriguingly the possibility of absolute asymmetric synthesis, which is the spontaneous formation of the excess of one of the enantiomers of the product, a dream of organic chemists for more than a century. The book contains expert-contributed chapters that describe the most exciting recent developments in the field of the Soai reaction and in related topics, ranging from mechanistic studies and theoretical research, to very practical problems in chiral syntheses and products. Features contributions from global experts, including several chapters from Kenso Soai and expert colleagues Focuses on recent developments in the field of asymmetric autocatalysis and newly reported findings Explores the Soai reaction, new developments, and the light it sheds on homochirality in certain biomolecules
Download or read book Catalytic Asymmetric Reactions of Conjugated Nitroalkenes written by Irishi N.N. Namboothiri and published by CRC Press. This book was released on 2020-08-13 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitroalkenes have often been referred to as "synthetic chameleons" owing to their reactivity, synthetic utility and biological significance. In the last two decades, the reactivity of nitroalkenes as substrates in diverse catalytic asymmetric transformations has been of tremendous interest on account of the powerful abilities of the nitro group to coordinate and withdraw electrons, as well as its amenability to undergo a wide variety of synthetic transformations. Although numerous original articles and reviews have appeared in the literature, a monograph providing a comprehensive coverage of this topic was conspicuous by its absence. This book features: A systematic, up-to-date, in-depth and well-organized compilation, spread over 12 chapters, of various catalytic asymmetric reactions of nitroalkenes with diverse substrates reported to date A wide coverage of reactions such as Michael additions, Friedel–Crafts reactions, cycloadditions, asymmetric reductions, multicomponent and cascade reactions, as well as other miscellaneous reactions Various chiral organo, metal and even biocatalysts involved in the stereoselective synthesis of multifunctional adducts via catalytic asymmetric reactions of nitroalkenes Schemes and figures detailing all the reagents, reaction conditions and product profiles Mechanistic details, including transition state models, which will be useful for effective catalytic design This book will be an invaluable resource for those who are working in the area of asymmetric catalysis and synthetic methodologies.
