Book Description
Over the past decade, much research effort has been devoted to the design and synthesis of new reagents and catalysts that can influence carbon-hydrogen bond activation, mainly because of the prospect that C−H activation could enable the conversion of cheap and abundant alkanes into valuable functionalized organic compounds. Alkane C-H Activation by Single-Site Metal Catalysis presents the current state-of-the-art development in the catalytic systems for the catalytic trans-formations of alkanes under homogeneous conditions. Chapter 1 offers a comprehensive summary of the main discoveries realized so far. Chapter 2 reviews the so-called electrophilic activation, initiated by Shulpín in the late 60s, and the base for the Catalytica system. Chapter 3 examines the catalytic borylation of alkanes, discovered by Hartwig, whereas chapter 4 provides an updated vision of the alkane dehydrogenation reaction. Chapter 5 covers the oxygenation of C-H bonds, a field of enormous interest with bioinorganic im-plications, and finally chapter 6 presents the functionalization of alkane C-H bonds by carbene or nitrene insertion. The history of C-H bond activation, and the current research described in this book, highlight the current research and present the reader with an outlook of this field which continues to be explored by an increasingly visionary and enthusiastic group of organic, organometallic, biological and physical chemists.

Book Description
Activation and Functionalization of C-H Bonds explores recent developments in the reaction chemistry of solution-phase transition-metal based systems with simple hydrocarbons and with more complex organic molecules. More than 20 internationally leading research groups contributed to this volume, and their chapters cover such topics as fundamental theoretical and mechanistic studies of C-H bond activation by metal complexes, catalytic systems for alkane functionalization, and new applications in synthetic organic chemistry. An introductory chapter offers an overview of stoichiometric and catalytic reactions of C-H bonds with transition metal complexes. The C-H bond is the most widespread linkage in organic chemistry, present in virtually every organic molecule. Unfortunately, C-H bonds are famously resistant to selective chemical transformations. The development of methods for their selective transformations has enormous potential value in fields ranging from the chemistry of fuels (for example, the conversion of methane to methanol) to the synthesis of the most complex organic molecules.

Book Description
Greener than conventional methods, C–H activation methods have flourished during the last decade and become especially attractive to organic chemists. Edited by a practioner in this rapidly developing field, C–H Bond Activation in Organic Synthesis provides an overview of this exciting playground of chemistry. The book summarizes the state of the art in C–H activation for functionalization, enabling you to carry out reactions in the most environmentally friendly fashion with the least contamination of by-products. The most popular C–H activation reactions are catalyzed by transition metals. This book dedicates a chapter to each of the following catalysts: palladium, rhodium, nickel, iron, copper, and cobalt. In addition, it covers radical-mediated C–H activation, fluorination via C–H activation, and C–H activation of heterocycles. Using a pedagogically practical approach, each chapter is divided by the transition metal catalyst, not a specific transformation. This gives you an up-to-date review of the most important topics of C–H activation. The area of C–H activation has experienced a flurry of activity over the past two decades, so the time is right for a resource that summarizes these powerful tools with which you can design and construct heteroaromatic molecules. Thus, direct C–H functionalization methods are expected to continue to greatly contribute to the mission of green chemistry: low-energy, waste-free, and atom-economic transformations for the synthesis of organic materials and biologically active molecules in the twenty-first century. Using this book, you can carry out environmentally friendly reactions that enable the conversion of cheap and abundant alkanes into valuable functionalized organic compounds.

Book Description
In this thesis, Xiaoshi Wang investigates the function and mechanism of a newly discovered heme-thiolate peroxygenase, AaeAPO. This enzyme class comes from Agrocybe aegerita and is used in the conversion of inert hydrocarbons to alcohols. Xiaoshi's work focuses on an extracellular P450 enzyme which is not limited in its stability and lack of solubility and therefore is relevant for widespread industrial use. The author demonstrates that the peroxygenase catalyzes a wide range of reactions. In some cases the author even describes very difficult transformations in molecules that are highly inert. Her detailed investigations provide a mechanistic framework for how the peroxygenase catalyzes such a large number of reactions. A major highlight of this thesis is the identification of key short-lived intermediates in the catalytic cycle of the peroxygenase, using rapid kinetic and spectroscopic methods, as well as the elucidation of the thermodynamic properties of these high-energy intermediates. This work adds new insight into an important class of enzymes.
