Download or read book Enantioselective Multicatalysed Tandem Reactions written by Helene Pellissier and published by Royal Society of Chemistry. This book was released on 2014-08-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chiral molecules are needed for the production of many pharmaceuticals and materials, and catalytic asymmetric synthesis provides a method for the preparation of such chiral products. For the synthesis of complex molecules, such as natural products and biologically active compounds, more than one catalytic reaction may be necessary and tandem catalysis refers to the combination of catalytic reactions into one synthesis. By combing catalysts it enables a more efficient, economical and selective one pot approach for complex molecule synthesis which could not be achieved through single specific catalytic systems. The challenge is finding the right catalyst which is compatible with other catalysts but also tolerates reagents, solvent and intermediates generated during the course of the reaction. Enantioselective Multicatalysed Tandem Reactions provides an overview of recent developments in the area. The first part of the book covers asymmetric tandem reactions catalysed by multiple catalysts from the same discipline (organocatalysts, two metal and multienzyme-catalysed reactions). The second part looks at tandem reactions catalysed by multiple catalysts from different disciplines including reactions catalysed by a combination of metals and organocatalysts, reactions catalysed by a combination of metals and enzymes, and finally reactions catalysed by a combination of organocatalysts and enzymes. The book will appeal to researchers and professionals in academic and industrial laboratories interested in catalysis, biocatalysis and organic synthesis of chiral compounds.

Download or read book Advances in Microwave assisted Heterogeneous Catalysis written by Jianli Hu and published by Royal Society of Chemistry. This book was released on 2023-11-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically the field of heterogeneous catalysis has focused on the design and optimisation of the catalytic materials. However, as these optimisations start to reach diminishing returns, attention has turned to non-conventional means for improving reaction conditions such as the use of ultrasound, plasma, electromagnetic heating and microwave heating. Microwave-assisted catalysis has been demonstrated to be useful in a wide range of applications including ammonia synthesis, desulfurization and production of chemicals from biomass. Advances in Microwave-assisted Heterogeneous Catalysis begins with the basics of microwave heating and the role of microwaves in heterogeneous catalysis. It goes on to cover the mechanisms of microwave specific reaction rate enhancement, microwave-assisted synthesis of porous, nonporous and supported metal catalysts, microwave augmented reactor technology and microwave-induced catalysis. The application of microwave-assisted heterogeneous catalysis in various fields of energy conversion, environmental remediation, and bulk and specialty chemicals synthesis are also discussed, making this a great reference for anyone involved in catalysis research.

Download or read book Catalytic Aerobic Oxidations written by Esteban Mejía and published by Royal Society of Chemistry. This book was released on 2020-07-14 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidation reactions are an important chemical transformation in both academia and industry. Among the major advances in the field has been the development of catalytic processes, which are not only selective and efficient, but also allow the replacement of common stoichiometric oxidants with molecular oxygen, ideally from air at atmospheric pressure. This results in processes with higher atom efficiency, where water is the only side product in line with the principles of green chemistry. Focusing on the use of molecular oxygen as the terminal oxidant, this book covers recent advances in both heterogeneous and homogeneous systems, with and without metals and on the “taming” of the highly reactive oxygen gas by use of micro-flow reactors and membranes. A useful reference for industrial and academic chemists working on oxidation processes, as well as green chemists.
Download or read book N Heterocyclic Carbenes written by Silvia Diez-Gonzalez and published by Royal Society of Chemistry. This book was released on 2016-11-08 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: In less than 20 years N-heterocyclic carbenes (NHCs) have become well-established ancillary ligands for the preparation of transition metal-based catalysts. This is mainly due to the fact that NHCs tend to bind strongly to metal centres, avoiding the need of excess ligand in catalytic reactions. Also, NHC‒metal complexes are often insensitive to air and moisture, and have proven remarkably resistant to oxidation. This book showcases the wide variety of applications of NHCs in different chemistry fields beyond being simple phosphine mimics. This second edition has been updated throughout, and now includes a new chapter on NHC‒main group element complexes. It covers the synthesis of NHC ligands and their corresponding metal complexes, as well as their bonding and stereoelectronic properties and applications in catalysis. This is complemented by related topics such as organocatalysis and biologically active complexes. Written for organic and inorganic chemists, this book is ideal for postgraduates, researchers and industrialists.

Download or read book Catalysis with Earth abundant Elements written by Uwe Schneider and published by Royal Society of Chemistry. This book was released on 2020-10-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalysis remains a key technology in a huge number of industrial processes in the 21st century. The catalytic properties of precious metals such as platinum and palladium are well understood. However, these metals are expensive and their supply is limited. Earth-abundant elements such as iron and nickel are, as the name suggests, in plentiful supply and much cheaper to use, but research on their use in catalysis has, historically, lagged behind. As researchers and companies increasingly look for ways to reduce costs and improve the sustainability of their processes there has been a renewed interest in these earth-abundant elements. This book presents a detailed overview of current research on the catalytic uses of the most Earth-abundant elements. Highlighting the top ten most Earth-abundant elements and their various roles in modern synthetic chemistry: s-block metals (Na, K, Mg, Ca), first-row transition metals (Ti, Mn, Fe), and p-block elements (Al, Si, P). The significant stoichiometric use of these elements, and their use as acid, base, dual, and/or redox catalysts will be discussed. It will be of use to industrial and academic researchers as well as graduate students with an interest in catalysis and sustainability.
