Book Description
Dehydrobenzene and Cycloalkynes deals with the problems associated with the production and reactions of dehydrobenzene and of the related fields of dehydroheterocycles and cycloalkynes. This book also describes the various synthetic applications of dehydrobenzene and provides a list of reactions in which dehydrobenzene occurs as an intermediary. The text explains the generation of dehydrobenzene by cleavage of cyclic systems, by photolytic methods, and by free radical reactions. Nucleophilic and electrophilic monodentate attacks on dehydrobenzene, as well as, bidentate additions to dehydrobenzene yielding cycloadducts. The book also notes that dehydrobenzene is not only a transition state but can be an intermediate of characteristic selectivity and lifetime. The reactions of dehydrobenzene in the gaseous phase affirm that the existence of dehydrobenzene is not restricted to the presence of a solvation shell. The researcher can then study the molecular structure of dehydrobenzene when its existence has been fully established. The text also extends the principle that the dehydroaromatic intermediates can be obtained by abstracting two adjacent hydrogen atoms from an aromatic substrate different from the 1- and 2- positions to arrive at a 1,3- and 1,4-dehydrobenzene. Researchers and scientists whose works are associated with organic chemistry, analytical chemistry, molecular physics or physical chemistry will find this book valuable.

Book Description
Thermal Electrocyclic Reactions explores the applications of thermal electrocyclic reactions to stereospecific synthesis. This book is divided into nine chapters, and begins with a presentation of the theory of electrocylic reactions using orbital conversions through symmetry operations and correlation diagrams. Considerable chapters are devoted to various conjugate systems entering an electrocyclic process, including two-electron, four electron-three-, four-, and five-atom, and six electron-five-, and six-atom systems. The remaining chapters examine the electrocyclic reaction of longer systems, including eight or more p electrons, as well as conjugated systems with an odd number of electrons, which constitute a special case in the conservation of orbital symmetry. This book will be of great value to organic chemists and researchers.

Book Description
Organic Chemistry, A Series of Monographs, Volume 5-C: Oxidation in Organic Chemistry covers the preparative use and the mechanistic aspects of the various oxidation reactions. This book contains five chapters that particularly consider oxidations that involve organoselenium intermediates. Chapter I describes the developments of selenium in organic chemistry, particularly the organoselenium reagents for performing selective oxidative transformations under unusually mild conditions. Chapter II deals with the problems encountered in oxygenation reactions carried out by several microorganisms, with an emphasis on a variety of fermentation techniques. Chapter III examines the oxidation of various organic peroxy acids and other peroxides, while Chapter IV discusses the oxidation with nitric acid or nitrogen oxides. Chapter V focuses on the properties of various oxidants and their application to hypohalite oxidation. This text will be of value to organic chemists, researchers, teachers, and students who are interested in oxidation of organic compounds.

Book Description
Ozonation in Organic Chemistry, Volume II: Nonolefinic Compounds discusses the reactions of ozone with organic compounds. The book presents the role of ozone in air pollution. It demonstrates the use of ozonation in wastewater purification, effects of ozone on biological systems, and degradation of rubber. The text describes the ozonation of acetylenic compounds, benzene, and substituted benzenes. It discusses the bond attack on benz-fused carbocyclics. Another topic of interest is the mechanism of ozonation of anthracene. The section that follows describes the electrophilic ozone attack on nitrogen. The book will provide valuable insights for chemists, environmentalists, students, and researchers in the field of organic chemistry.

Book Description
Organic Chemistry, Second Edition, Volume I: Organic Functional Group Preparations provides a convenient and useful source of reliable preparative procedures for the most common functional groups. This book discusses the preparations of each group that are subdivided into different reaction types, including elimination, condensation, and oxidation and reduction reactions. Organized into 21 chapters, this edition begins with an overview of the reduction methods that allow the preparation of hydrocarbon of known structure. This text then explores the acid-catalyzed of thermal elimination of water from alcohols, which is a common laboratory method for the preparation of olefins. Other chapters consider the two most significant synthetic methods for introducing an acetylenic group into the molecule, which involve the elimination of hydrogen halides. This book discusses as well the importance of oxidation reactions. The final chapter deals with sulfonation reactions. This book is a valuable resource for organic chemists and research workers.

Book Description
Carbon-13 NMR Spectroscopy focuses on the potential of 13C techniques and the practical difficulties associated with the detection of 13C NMR absorption. This monograph includes a descriptive presentation of 13C shielding results that has been adopted with emphasis on the structural and stereochemical aspects. Organized into four parts encompassing 11 chapters, this book starts with an overview of the characteristics of the NMR signals derived from compounds containing 13C nuclei in natural abundance that are inherently much weaker than those exhibited by protons. This monograph then compares the primary characteristics of 13C NMR with the more familiar proton methods. Other chapters consider the 13C spectra of pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and s-tetrazine. The final chapter deals with the effects of solute–solvent interactions on the shieldings of other nuclei. This monograph is intended for organic chemists, graduate students, and researchers in various branches of chemistry with an interest in 13C NMR methods as another approach to chemical problems.

Book Description
Cyclophanes, Volume II, provides a comprehensive review of the field of cyclophane chemistry for the period between the earlier volume in this series (Bridged Aromatic Compounds by A. H. Smith, 1964) and the present (generally through 1981). An attempt has been made to provide a selection of topics that delineate the past and present of cyclophane chemistry and point toward some of its future directions. The ordering of chapters has been chosen to present background, theory, structure, and spectroscopy followed by a somewhat arbitrary division of cyclophanes into subgroups, roughly in order of increasing structural complexity. Key topics discussed include the synthesis and properties of heterophanes, condensed benzenoid and nonbenzenoid cyclophanes, multibridged and multilayered cyclophanes, cyclophanes in host-guest chemistry, and cyclophanes as synthetic analogs of enzymes and receptors. Individual chapters have been written so that they may be read with little or no direct reference to other chapters. Each stands alone as a review of a particular area of cyclophane chemistry and therefore some overlap between chapters will be apparent.
