  • Dehydrobenzene and Cycloalkynes

    • 1 Edición
    • Reinhard W. Hoffmann
    • Inglés
    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.

    • Inglés
    Symmetry in Coordination Chemistry provides a comprehensive discussion of molecular symmetry. It attempts to bridge the gap between the elementary ideas of bonding and structure learned by freshmen, and those more sophisticated concepts used by the practicing chemist. The book emphasizes the use of symmetry in describing the bonding and structure of transition metal coordination compounds. The book begins with a review of basic concepts such as molecular symmetry, coordination numbers, symmetry classification, and point group symmetry. This is followed by separate chapters on the electronic, atomic, and magnetic properties of d-block transition elements; the representation of orbital symmetries in a manner consistent with the point group of a molecule. Also included are discussions of vibrational symmetry; crystal field theory, ligand field theory, and molecular orbital theory; and the chemistry of a select few d-block transition elements and their compounds. This book is meant to supplement the traditional course work of junior-senior inorganic students. It is for them that the problems and examples have been chosen.

  • Handbook of Naturally Occurring Compounds V2

    • T.K. Devon
    • Inglés
    Handbook of Naturally Occurring Compounds, Volume II: Terpenes is a handbook of naturally occurring compounds to which structures have been assigned, with particular reference to terpenes. Each structure is stored in the handbook with its name, molecular formula, molecular weight, optical rotation, melting point, literature reference, and classification number. Comprised of 10 chapters, this volume begins with an overview of terpenes and their classification schemes, followed by terpenoid classes and their structural/biogeneti... categories as well as skeletons: monoterpenes, sesquiterpenes, diterpenes, sesterterpenes, triterpenes, steroids, carotenoids, and polyprenoids. Miscellaneous compounds of terpenoid origin are also considered, including the ionones and fraxinellone. This final category for miscellaneous compounds of terpenoid origin arises through the somewhat frequent occurrence of oxidative degradation in terpenoid biosynthesis. In general these compounds have degraded structures such that there exists some ambiguity as to their precise biosynthetic precursors. Each individual compound possesses a compound sequence number which, in combination with the Classification Code Number, supplies a unique address for that compound. This book should be a valuable resource for chemists as well as students and researchers of chemistry.

    • Inglés
    Simple Dense Fluids is a nine-chapter text that explores the chemistry and physics of simple fluid systems. Simple systems primarily include the noble gases, the homonuclear diatomic molecules, and a select group of some polyatomic but spherically symmetrical molecules. The opening chapter describes the change of thermodynamic functions along the saturation line and how these functions can best be obtained from sets of measurements that are often in conflict, with an emphasis on the functions of three simple liquids: argon, nitrogen, and oxygen. The following chapter outlines the basic thermodynamic and statistical mechanical ideas that have been applied to the liquid-vapor interface, followed by a summary of surface tension data of simple fluids. Considerable chapters are devoted to X-ray, light, and neutron scattering measurements on simple dense fluids. This book further discusses the use of electromagnetic data, especially the dielectric constant and refractive index, in the interpretation of molecular interactions and molecular structure. The available experimental data on several nonpolar liquids and liquid mixtures are also provided. The final chapters survey the nuclear relaxation and spectroscopic data in simple liquids. These chapters also present experimental data relevant to transport phenomena in simple fluids. Workers and researchers in the field of simple dense fluids will find this book of great value.

  • Reactive Free Radicals

    • 1 Edición
    • J Hay
    • Inglés
    Reactive Free Radicals deals with the chemistry of reactive free radicals. The initial premise is that the reactivity of a free radical depends upon its shape and therefore upon the character of the orbital(s) containing the unpaired electron. Based on this premise, a possible explanation for some of the fascinating phenomena observed in a number of free radical reactions such as combustion and pyrolysis is offered. This book is comprised of five chapters and begins with a brief overview of the chemistry of free radicals, what they are and how they are formed, and their structure and reactivity. The emphasis is on those characteristics of free radicals attributable directly to the unpaired electron function. The reader is then introduced to the techniques used for the determination of the structure of free radicals, including electron spin resonance spectroscopy, nuclear magnetic resonance spectroscopy, and infrared spectroscopy. Subsequent chapters focus on bond dissociation energies and some of the complications arising from polar and non-polar effects in free radical reactions. This monograph should serve as a valuable reference for organic chemists as well as undergraduate and graduate students of organic chemistry.
