    • Inglés
    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.

    Advances in Magnetic Resonance, Volume 3, describes a number of important developments which are finding increasing application by chemists. The book contains five chapters and begins with a discussion of how the properties of random molecular rotations reflect themselves in NMR and how they show up, often differently, in other kinds of experiments. This is followed by separate chapters on the Kubo method, showing its equivalence to the Redfield approach in the cases of most general interest; the current state of dynamic nuclear polarization measurements in solutions and what they tell us about the interactions of molecules and about the frequency spectra of molecular motions; and insights into the structures of ferroelectric crystals and the nature of the transition to the ferroelectric state. The final chapter discusses spin temperatures and related matters.

    • Inglés
    Piperidine, one of the simplest heterocyclic systems, is found in nature as part of several alkaloid compounds. Both natural and especially unnatural piperidine derivatives present interesting pharmacological properties. From a structural viewpoint, the conformation of piperidine has been the subject of one of the fiercest controversies in structural organic chemistry in the last few years. As a result of the combined use of several spectroscopic techniques, the conformational behavior of most types of piperidine-related compounds has been clarified. Some piperidine derivatives, namely, N-acylpiperidine, &agr;-cyanopiper... and piperidones are extremely useful and versatile intermediates in organic synthesis. The present book offers an updated and integrated view of all these topics. The aim of the book is twofold. Firstly, to reveal to the reader the combined use of different spectroscopic data, to facilitate an insight into the structure and conformational properties of any new piperidine derivative. Secondly, to establish a consistent link between conformation and reactivity for a variety of piperidine derivatives. Such a bridge is a key step for stereocontrol when dealing with the application of piperidine derivatives as synthetic intermediates. The book is conceived so that most of the information comes from visual inspection of the very abundant graphic material. An exhaustive subject index of more than 450 entries is also included.

    • Inglés
    Intermetallic Compounds in Mercury is Volume 51 of the Solubility Data Series. It follows Volume 25, Metals in Mercury, of the same series. Evaluations of more than fifty systems are presented together with all of the data and citations from the original literature. In addition, over 200 references are given to related literature that describes metal interactions in amalgams but from which quantitative information can only be inferred. For each compound reported, a critical evaluation presents recommended or tentative values of solubilities or solubility products based on statistical treatment of the data reported. Mercury provides a unique solvent for metal-metal reactions, and thus the data reported here are a valuable addition to the experimental basis for better fundamental understanding of interactions of metals in the elemental state. In addition, this material is important technologically in the areas of metal processing, materials, and electrochemistry.
