Book Description
hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known to be the less reactive organic compounds. Saturated hydrocarbons may be called the “noble gases of organic chemistry” and, if so, the first representative of their family – methane – may be compared with extremely inert helium. As in all comparisons, this parallel between noble gases and alkanes is not fully accurate. Indeed the transformations of alkanes, including methane, have been known for a long time. These reactions involve the interaction with molecular oxygen from air (burning – the main source of energy!), as well as some mutual interconversions of saturated and unsaturated hydrocarbons. However, all these transformations occur at elevated temperatures (higher than 300–500 °C) and are usually characterized by a lack of selectivity. The conversion of alkanes into carbon dioxide and water during burning is an extremely valuable process – but not from a chemist viewpoint.

Book Description
The Chemistry of Catalytic Hydrocarbon Conversions covers the various chemical aspects of catalytic conversions of hydrocarbons. This book is composed of eight chapters that include catalytic synthesis of hydrocarbons from carbon monoxide, hydrogen, and methanol. The opening chapters examine various acid- and base-catalyzed reactions, such as isomerization, polymerization, oligomerization, alkylation, catalytic cracking, reforming, hydrocracking, and hydrogenation. The subsequent chapters are devoted to specific catalytic reactions, including heterogeneous hydrogenation, dehydrogenation, aromatization, and oxidation. Other chapters describe the homogeneous catalysis by transition metal organometallic catalysts and the metathesis of unsaturated hydrocarbons. The concluding chapter deals with the synthesis of liquid hydrocarbon fuels from carbon monoxide, hydrogen, methanol, and dimethyl ether. This book is of great benefit to petroleum chemists, engineers, and researchers.

Book Description
The collection of contributions in this volume presents the most up-to-date findings in catalytic hydrogenation. The individual chapters have been written by 36 top specialists each of whom has achieved a remarkable depth of coverage when dealing with his particular topic. In addition to detailed treatment of the most recent problems connected with catalytic hydrogenations, the book also contains a number of previously unpublished results obtained either by the authors themselves or within the organizations to which they are affiliated.Because of its topical and original character, the book provides a wealth of information which will be invaluable not only to researchers and technicians dealing with hydrogenation, but also to all those concerned with homogeneous and heterogeneous catalysis, organic technology, petrochemistry and chemical engineering.

Book Description
The domain of catalytic hydrogenation continues to grow fast, reflecting the wide range of chemical applications that can be enhanced by the easy use of molecular hydrogen. The advances in characterization techniques and their application have improved our understanding of the catalytic processes and mechanisms occurring in both homogeneous and heterogeneous catalysis. The aim of this volume, although not exhaustive, is to provide a general overview of new progress of the hydrogenation reactions. This volume comprises a series of various contributions, as reviews or original articles, treating heterogeneously and homogeneously catalyzed hydrogenation reactions. It is composed of three parts: hydrogenation reactions in fine organic chemistry, hydrogenation reactions in environmental chemistry and renewable energy, and special topics in hydrogenation.

Book Description
This unique book, drawing on the author’s lifetime experience, critically evaluates the extensive literature on the field of Metal-Catalysed Reactions of Hydrocarbons. Emphasis is placed on reaction mechanisms involving hydrogenation, hydrogenolysis, skeletal and positional isomerisation, and exchange reactions. The motivation for fundamental research in heterogeneous catalysis is to identify the physicochemical characteristics of active centres for the reaction being studied, to learn how these may be modified or manipulated to improve the desired behavior of the catalyst, and to recognize and control those aspects of the catalyst's structure that limit its overall performance. By restricting the subject of the book to hydrocarbons, Bond has progressively developed the subject matter to include areas of importance both to researchers and to those working in the industry.

Book Description
Homogeneous hydrogenation is one of the most thoroughly studied fields of homogeneous catalysis. The results of these studies have proved to be most important for an understanding of the underlying principles of the activation of small molecules by transition metal complexes. During the past three decades homogeneous hydrogenation has found widespread application in organic chemistry, including the production of important pharmaceuticals, especially where a sophisticated degree of selectivity is required. This volume presents a general account of the main principles and applications of homogeneous hydrogenation by transition metal complexes. Special attention is devoted to the mechanisms by which these processes occur, and the role of the recently discovered complexes of molecular hydrogen is described. Sources of hydrogen, other than H2, are also considered (transfer hydrogenation). The latest achievements in highly stereoselective hydrogenations have made possible many new applications in organic synthesis. These applications are documented by giving details of the reduction of important unsaturated substrates (alkenes, alkynes, aldehydes and ketones, nitrocompounds, etc.). Hydrogenation in biphasic and phase transfer catalyzed systems is also described. Finally, a discussion of the biochemical routes of H2 activation highlights the similarities and differences in performing hydrogenation in both natural and synthetic systems. For researchers working in the fields of homogeneous catalysis, especially in areas such as pharmaceuticals, plastics and fine chemicals.

Book Description
Base-Catalyzed Reactions of Hydrocarbons and Related Compounds focuses on the use of bases as catalysts for the conversion of hydrocarbons and related compounds. In order to emphasize the broad scope of base-catalyzed reactions, examples dealing with the conversion of non-hydrocarbons are given. Comprised of 14 chapters, this book begins with a historical overview of base-catalyzed conversions of hydrocarbons, followed by a discussion on the isomerization of olefins, acetylenes, and allenes, as well as the dimerization and oligomerization of hydrocarbons. The reader is then introduced to a variety of reactions, including those between aromatic hydrocarbons and olefins and between alkylpyridines and alkenylpyridines; homogeneous carbon-carbon addition reactions; and reactions of aprotic solvents with olefins. Subsequent chapters explore carbon-carbon addition of olefins with miscellaneous compounds; addition of ammonia, amines, and anilines to olefinic hydrocarbons; hydrogenation and oxygenation; dehydrogenation, aromatization, and hydrogen transfer; and dehydration of alcohols. This monograph will be of interest to chemists.
