This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidation reactions are among the most important transformations in organic chemistry and have enormous potential to streamline the synthesis of complex organic molecules. Aerobic oxidations are especially appealing since they circumvent the use of toxic, stoichiometric reagents that result in poor atom economy and intractable waste. However, few aerobic oxidation methods employ catalysts with suitable stability, activity, and/or selectivity to impact industrial organic chemical synthesis. Metalloenzymes that catalyze selective aerobic oxidation reactions in nature often work cooperatively with redox-active cofactors and coenzymes to achieve efficient aerobic turnover and provide a valuable framework for development of new catalysts. Herein are reported studies of oxidation reactions featuring a homogeneous or heterogeneous catalyst working cooperatively with a homogeneous cocatalyst to enable efficient organic oxidation reactions. Chapter 1 highlights the challenges associated with developing efficient aerobic oxidation manifolds and analyzes the thermodynamic principles underlying catalytic aerobic oxidation reactions. A series of case studies are used to highlight the implications of catalyst and cocatalyst potentials on the activity and selectivity in the context of chemical synthesis. These insights are used as a backdrop for the content in subsequent chapters. Chapter 2 describes the first aerobic oxoammonium generation with a heterogeneous catalyst and lays the foundation for the content in Chapter 3, which discloses the first example of a metal on nitrogen-doped carbon (MNC) working cooperatively with a nitroxyl cocatalyst to effect alcohol oxidation. Chapter 4 details the development of an eminently scalable Pd/HQ-cocatalyzed cis-selective diacyloxylation of cyclohexadiene. Chapter 5 describes the study and development of a highly efficient palladium aerobic C-H arylation catalyst through the mechanistically-guided development of new quinone cocatalysts.

Available in PDF, EPUB and Kindle. Book excerpt: This brief summarizes the role of certain catalysts and associated processes that are involved in the reduction or elimination of hazardous substances from wastewater and the exploitation of renewable raw materials. The authors begin by providing a summary of the most recent developments in catalysts used in the advanced oxidation of organic pollutants in aqueous phase. Advanced Oxidation Processes (AOPS) are described in terms of homogeneous and heterogeneous catalysts. Some emphasis is placed on the role nanocatalysts, perovskite-type catalysts, and green catalysts play in several AOPs such as Fenton Chemistry, photocatalytic oxidation, and the hybrid technologies that combine different processes. Catalyst preparation, characterization, reaction chemistry, and process technology are described. Specific wastewater case studies which illustrate the role of these catalysts in AOPs completes the brief.

Download or read book Selective Oxidation by Heterogeneous Catalysis written by Gabriele Centi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective Oxidation by Heterogeneous Catalysis covers one of the major areas of industrial petrochemical production, outlining open questions and new opportunities. It gives keys for the interpretation and analysis of data and design of new catalysts and reactions, and provides guidelines for future research. A distinctive feature of this book is the use of concept by example. Rather than reporting an overview of the literature results, the authors have selected some representative examples, the in-depth analysis of which makes it possible to clarify the fundamental, but new concepts necessary for a better understanding of the new opportunities in this field and the design of new catalysts or catalytic reactions. Attention is given not only to the catalyst itself, but also to the use of the catalyst inside the process, thus evidencing the relationship between catalyst design and engineering aspects of the process. This book provides suggestions for new innovative directions of research and indications on how to reconsider the field of selective oxidation from different perspectives, outlining that is not a mature field of research, but that new important breakthroughs can be derived from fundamental and applied research. Suggestions are offered on how to use less conventional approaches in terms of both catalyst design and analysis of the data.

Available in PDF, EPUB and Kindle. Book excerpt: Apply an Omnibus of Knowledge from Leaders in the Field The unexpected diversity of topics presented at previous gatherings forced organizers of 2008’s 22nd Conference on Catalysis of Organic Reactions to expand its format to reflect the remarkable current degree of specialization in the field. Catalysis of Organic Reactions contains a compilation of papers presented at the event, and subsequently, few books will be able to match the breadth and depth of its content. Featuring papers by respected scientists from academia, industry, and the governmental research-and-development sector, it covers various aspects of the production, sale, and use of catalysts for practical purposes. Articles concentrate on the general area of catalyzed synthesis, emphasizing the production of organic chemicals. With a focus on application rather than theory, the dominant theme is the traditionally practiced area of heterogeneous catalysis. Topics include: Hydrogenation and hydrogenolysis C-C coupling Amination and oxidation (including the precious metal, supported base metal, and sponge metal, Raney process, and homogeneous catalyst types) End uses of products, including industrial petrochemicals, fine chemicals, and pharma intermediates Those working with applied catalysis will benefit greatly from this consolidation of insights and reviews of the latest developments in the field. Each of the papers presented were edited by ORCS members, drawn from both academia and industry, and peer-reviewed by experts in related fields of study.
