Book Synopsis Ions and Ion Pairs and Their Role in Chemical Reactions by : J. Smid
Download or read book Ions and Ion Pairs and Their Role in Chemical Reactions written by J. Smid and published by Elsevier. This book was released on 2013-09-03 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ions and Ion Pairs and their Role in Chemical Reactions covers a wide spectrum of ion pairing phenomena. This book focuses on the structure, dynamics, and energetics of ions and ion pairs and their complexes with solvent molecules and ion coordinating ligands in the solid, liquid, and gaseous state. Organized into 12 chapters, this book begins with an overview of the theory and complications involved in dipole moment measurements in slightly conductive polar solvents. This text then explores the measurement of gas phase ion-molecule equilibria by special spectrometric methods. Other chapters consider the NMR experiments on potassium biphenyl, sodium biphenyl, and rubidium biphenyl, dissolved in different solvents. This book discusses as well the ion pair formation of some cyclic conjugated carbanions and nitranions. The final chapter deals with the information obtained from relaxation measurements on processes such as ionic dissociation, aggregation, and solvent separation. This book is a valuable resource for chemists, organic chemists, and quantum chemists.
Book Synopsis Crown Ethers and Phase Transfer Catalysis in Polymer Science by : Lon Mathias
Download or read book Crown Ethers and Phase Transfer Catalysis in Polymer Science written by Lon Mathias and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase transfer catalysis or interfacial catalysis is a syn thetic technique involving transport of an organic or inorganic salt from a solid or aqueous phase into an organic liquid where reaction with an organic-soluble substrate takes place. Over the past 15 years there has been an enormous amount of effort invested in the development of this technique in organic synthe sis. Several books and numerous review articles have appeared summarizing applications in which low molecular weight catalysts are employed. These generally include either crown ethers or onium salts of various kinds. While the term phase transfer catalysis is relatively new, the concept of using a phasetrans fer agent (PTA) is much older~ Both Schnell and Morgan employed such catalysts in synthesis of polymeric species in the early 1950's. Present developments are really extensions of these early applications. It has only been within the last several years that the use of phase transfer processes have been employed in polymer synthesis and modification. Similarly, the use of polymer-bound phase transfer agents is also a recent development. These and related areas have nonetheless enjoyed explosive growth as mea sured by the number of publications and the variety of applica tions which have appeared. Several reviews dealing with these l 6 polymer-related investigations have been published.

Book Synopsis Polymerization of Heterocycles (Ring Opening) by : S. Penczek
Download or read book Polymerization of Heterocycles (Ring Opening) written by S. Penczek and published by Elsevier. This book was released on 2016-02-03 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymerization of Heterocycles (Ring Opening) is a collection of papers presented at the International Symposium on Polymerization of Heterocycles (Ring-Opening) held in Warsaw, Poland on June 23-25, 1975. The first paper describes the developments and physical meaning of ion pairs and higher ionic aggregates. Another paper explains the process of obtaining linear polymers, containing rings in the main chain. The book interprets the various behaviors of polymers that can result in high optical yields of stereoelectivity ratios equal to 8. The text then discusses future trends in aldehyde and carbonyl polymerization, including some problem areas pertaining to failures to homopolymerize or copolymerize tetrachloroethylene oxide. Another paper reviews the elemental reactions of selected combinations of copolymerization; the next paper discuses aspects of the mechanism of nucleophilic opening of epoxide rings through studies of certain kinetics. The book then analyzes the ability of lactams to undergo ring-opening polymerization, which mainly depends on the ring size and on the substitution and presence of heteroatoms in the lactam ring itself. The text also discusses the preparation, properties, and applications of the heterochain polymers in medicine or biologically active materials. The book can provide useful information for biochemists, researchers dealing with inorganic and organic compounds, and scientists working in the fields of chemistry such as synthetic chemistry, as well as polymer engineering.

Available in PDF, EPUB and Kindle. Book excerpt: of Polymer Chemistry, Inc. of the American Chemical Society held its The Division 15th Biennial Polymer Symposium on the topic, "Advances in New Materials," November 17-21, 1990, at the Pier 66 Resort and Marina in Ft. Lauderdale, Florida. A three and one half day program was presented by recognized leaders in major areas of new polymeric materials. The topics of the Biennial Symposium included new high performance polymers, polymers for electronic applications, electrically conducting polymers, nonlinear optics, new polymer systems, and polymers derived from biological media. These are the subject areas of this volume of "Contemporary Topics in Polymer Science". The intent of the Symposium was to focus on recent advances in polymeric materials. The technical sessions were complemented by an initial poster session which augmented the various technical sessions. A particular highlight of the meeting was the presentation to Professor Michael Szwarc of the 1990 Division of Polymer Chemistry Award by Dr. J. L. Benham, Chairman of the T Aymer Division. During his Award address, Professor Szwarc described how he had become a polymer chemist and later developed "living polymers." Without a doubt, Professor Szwarc has made a profound contribution to the polymer field, which has yielded many new forms of living polymerization.

Book Synopsis Crown Ethers and Analogous Compounds by : M. Hiraoka
Download or read book Crown Ethers and Analogous Compounds written by M. Hiraoka and published by Elsevier. This book was released on 2016-05-04 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of crown ethers by Pedersen in 1967, several thousands of crown ethers and analogous compounds have been synthesized. Their specific characteristics have been investigated and a variety of applications developed. These developments have led to new fields of chemistry called host-guest chemistry and supramolecular chemistry. This book presents the state-of-the-art of the chemistry of crown ethers and analogous compounds. The first chapter provides an orientation in the new fields of chemistry. Chapter 2 reviews advances in synthetic procedures for crown ethers and analogous compounds including azacrown ethers, thiacrown ethers, functionalized crown ethers, cryptands and others. The focus of chapter 3 is on the concept and synthetic strategies for the molecular design of new crown compounds. Chapters 4-7 are concerned with noteworthy topics in the applications of crown compounds. Chapter 4 deals with the application to ion-selective electrodes and liquid chromatography, both of which are the most important targets in the analytical application of crown compounds. One major application of crown ethers is the design and syntheses of artificial molecules which can catalyze a useful synthetic reaction in an enzyme-mimetic reaction manner, through novel non-covalent complexes. The strategies for enzymatic modelling with crown ethers are covered in chapter 5, while chapter 6 presents the principle of amine-selective colour complexation and its application. In chapter 7 switched-on crown ethers that can respond to environmental stimuli are reviewed. The final chapter is devoted to a wide-ranging discussion of developments in macrocyclic polyamine chemistry. Unlike crown ethers, macrocyclic polyamines, bearing nitrogen donor atoms which belong to a soft base, form complexes with ions of transition metals and heavy metals which are classified as soft acids. Therefore, macrocyclic polyamines are expected to have very versatile applications. Scientists in chemistry, biochemistry, physical organic chemistry, pharmaceutical chemistry and industrial chemistry will find this book a helpful summary and a stimulating contribution to research in this specialized field of crown compounds.
