Synopsis Polyoxomolybdates as Green Catalysts for Aerobic Oxidation by : Anjali Patel

Heterogeneously catalyzed selective oxidations of alcohols is a highly topical field. The first chapter of this brief describes the importance of the selective oxidation of alcohols and advantages of heterogeneous catalysts over conventional catalysts, use of environmentally benign oxidants, and the design of selective catalysts by tailoring of polyoxometalates at the molecular level. Chapter 2 describes synthesis, characterization 11-molybdophosphate based supported materials and their use as heterogeneous catalysts for oxidation of alcohols with molecular oxygen under solvent free mild reaction condition. ZrO2, Al2O3, MCM-41 and zeolite Hβ were used as supports. Chapter 3 describes synthesis, characterization of transition metals (Mn, Co, Ni, Cu)- substituted phosphomolybdates and their use as heterogeneous catalysts for oxidation of alcohols with molecular oxygen under solvent free mild reaction condition. Chapter 4 describes conclusive remarks for present catalytic systems.

Synopsis Frontiers of Green Catalytic Selective Oxidations by : Konstantin P. Bryliakov

The demand for novel efficient and environmentally sustainable chemo, regio- and stereoselective catalyst systems for the oxidation of organic substrates is continuously growing in line with toughening economic and environmental constraints. This book addresses these issues; it consists of eleven chapters written by world-recognized experts in green and sustainable oxidation catalysis. The most urgent and challenging topics, in the judgment of the editor, such as green asymmetric epoxidations, sulfoxidatiuons, C–H oxidations; oxidation catalysis by polyoxometalates and oxidations in non-conventional solvents, etc. have been critically reviewed in this book. Both fundamental aspects, such as catalysts design, catalytic properties, nature of catalytically active sites and reaction mechanisms, and practical outlook of the oxidations have been addressed by the authors. The book appeals to a broad readership, particularly graduate students, employees of universities and research organizations, and industrial researchers, particularly those working in the areas of homogeneous oxidation catalysis, asymmetric synthesis, organocatalysis, sustainable catalytic processes and green chemistry, mechanisms of catalytic reactions, synthesis of bioactive compounds, biomimetic chemistry, etc. Konstantin Bryliakov is Leading Researcher at the Boreskov Institute of Catalysis. In 2016, he was elected Honorary Professor of the Russian Academy of Sciences.

Synopsis Leveraging Heterogeneous Metal on Nitrogen-doped Carbon Materials for Aerobic Oxidation Catalysis by : Melissa Nicole Hall

Chemical redox reactions serve as an important class of transformations for the modernchemist, and advancements in homogeneous and heterogeneous catalysis are ever expanding the synthetic toolbox. Nonprecious metal catalysts and "green" reagents are sought after for their economic and environmental advantages to synthetic chemistries, and bridging seemingly disparate fields can lead to intriguing insights and developments. For decades, first-row transition metals incorporated into nitrogen-doped carbon (MNCs) have been studied for electrochemical oxygen reduction as leading alternatives to platinum in fuel cells, and more recently, MNCs have been used as catalysts for aerobic oxidation reactions in the context of organic synthesis. In this approach, protons and electrons from chemical bonds in organic molecules are used to promote oxygen reduction as balanced redox half reactions. This body of work describes our recent developments with MNC materials and their applications in organic synthesis. Chapter 1 offers an overview of MNC synthesis and characterization followed by a synopsisof the application of MNC catalysts to thermal organic transformations. This provides important context for Chapter 2 wherein we disclose our recently developed protocol for the incorporation of atomically-dispersed iron sites into nitrogen-doped carbon frameworks. The resulting MNC materials are then characterized in a cross-laboratory study targeting the quantification of active sites on MNCs prepared via diverse synthetic protocols. Chapter 3 presents the development of catalytic conditions for the formation of diazo compounds using oxygen as the terminal oxidant, initially by means of homogeneous copper catalysts. We then leveraged MNC catalysts for the same transformation and paired the formation of diazo compounds with enantioselective carbene transfer to achieve C-H insertion and cyclopropanation. This new MNC reactivity is further showcased in a flow reactor with gram-scale synthesis of diazo compounds. Chapter 4 describes ongoing work seeking to understand MNC-catalyzed hydrazone oxidation, including mechanistic insights, structure-activity relationships, and broadening this reactivity to other transformations involving proton-coupled electron transfers.
