Addition Reactions With Unsaturated Hydrocarbons

Addition Reactions with Unsaturated Hydrocarbons Provides comprehensive coverage of the atom-economic approach to functionalized molecules using unsaturated hydrocarbons as starting materials Unsaturated hydrocarbons have emerged as an important class of fundamental starting materials in organic synthesis. Synthetic methodologies incorporating unsaturated hydrocarbons continue to expand due to their numerous applications in the synthesis of a vast array of chemicals. Addition Reactions with Unsaturated Hydrocarbons presents an up-to-date overview of modern methods that utilize reactions of unsaturated hydrocarbons as building blocks of organic synthesis, covering the conceptual and practical knowledge required for designing atom-efficient reactions to synthesize functionalized molecules. This authoritative volume discusses homo-dimerization and cross-dimerization of alkynes and/or alkenes, synthesis of carbonyl compounds from the hydration of alkynes, cycloadditions of alkynes and alkenes for the synthesis of carbocycles and heterocycles, double functionalization of alkynes and alkenes by addition reactions of element-element bonds, and more. Summarizes the most recent developments in the reactions of unsaturated hydrocarbons Features more than 600 schemes describing typical reactions starting from unsaturated hydrocarbons Covers topics such as alkynylated reactions, addition and cycloaddition reactions of alkynes and alkenes, and carbonylation of alkynes and alkenes with carbon monoxide Includes examples of synthesis procedures of natural products involving alkyne transformation With comprehensive coverage of important reactions of unsaturated hydrocarbons, Addition Reactions with Unsaturated Hydrocarbons is a valuable resource for organic chemists, pharmaceutical chemists, and biochemists in both academia and industry as well as an excellent reference text for graduate students in relevant areas of chemistry.

The first edition of this book, published in 1966, received wide acclaim. This new edition has been almost entirely rewritten and expanded to incorporate the extensive research done in this field over the last two decades. The book provides a unified treatment, from a mechanistic viewpoint, of those reactions of unsaturated organic compoiunds which, being initiated by co-ordination with an electrophilic reagent, proceed through intermediates having cationic character, and are completed by the formation of products of addition. After a brief account of the properties of carbocations, electrophilic reagents are considered in accordance with their position in the Periodic Table of the elements.

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.

In organic chemistry, Alkenes, also known as olefins, are the unsaturated hydrocarbons with the general formula of CnH2n that contains one or more carbon-carbon double bonds in their chemical structures (RC=CR'). The presence of this double bond allows alkenes to react in ways that alkanes cannot. Hence, alkenes find many diverse applications in industry. These compounds are widely used as initial materials in the synthesis of alcohols, plastics, lacquers, detergents, and fuels. The current book includes all knowledge and novel data according to the structure of alkenes, their novel synthesis methods, and their applications. In addition, manufacture, properties, and the use of polyalkenes are the other important topics that are covered in this book. These data are collected by the efforts and contributions of many authors and scientists from all over the globe, and all of us are ready to further improve the contents of this book as per the readers' comments.

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.
