Download or read book The Anomeric Effect written by Eusebio Juaristi and published by CRC Press. This book was released on 1994-10-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of the structural, conformational, and chemical manifestations of the anomeric effect. In order to present a cogent discussion of this most fundamental and relevant phenomenon, three chapters examine our present understanding of the origin of this conformational effect, based upon a wealth of theoretical and physical data. Equally important, however, are three additional chapters that deal with the general consequences of the stereoelectronic interactions that are associated with the basis of the anomeric effect. The remainder of the book is devoted to new areas of development in the topic-such as differentiation of the endo and exo anomeric interactions, specific analysis of the enthalpic component of anomeric effects, critical evaluation of the kinetics and reverse anomeric effects, discovery of a new substantial effect in second- and lower-row anomeric segments, and others.

This book was released on 2013-06-29 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although numerical data are, in principle, universal, the compilations presented in this book are extensively annotated and interleaved with text. This translation of the second German edition has been prepared to facilitate the use of this work, with all its valuable detail, by the large community of English-speaking scientists. Translation has also provided an opportunity to correct and revise the text, and to update the nomenclature. Fortunately, spectroscopic data and their relationship with structure do not change much with time so one can predict that this book will, for a long period of time, continue to be very useful to organic chemists involved in the identification of organic compounds or the elucidation of their structure. Klaus Biemann Cambridge, MA, April 1983 Preface to the First German Edition Making use of the information provided by various spectroscopic tech niques has become a matter of routine for the analytically oriented organic chemist. Those who have graduated recently received extensive training in these techniques as part of the curriculum while their older colleagues learned to use these methods by necessity. One can, therefore, assume that chemists are well versed in the proper choice of the methods suitable for the solution of a particular problem and to translate the experimental data into structural information.

Download or read book High resolution NMR Techniques in Organic Chemistry written by T. Claridge and published by Elsevier. This book was released on 1999-12-24 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the initial observation of proton magnetic resonance in water and in paraffin, the discipline of nuclear magnetic resonance has seen unparalleled growth as an analytical method. Modern NMR spectroscopy is a highly developed, yet still evolving, subject which finds application in chemistry, biology, medicine, materials science and geology. In this book, emphasis is on the more recently developed methods of solution-state NMR applicable to chemical research, which are chosen for their wide applicability and robustness. These have, in many cases, already become established techniques in NMR laboratories, in both academic and industrial establishments. A considerable amount of information and guidance is given on the implementation and execution of the techniques described in this book.
Download or read book Physical Methods in Heterocyclic Chemistry written by A. R. Katritzky and published by Elsevier. This book was released on 2013-10-22 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Methods in Heterocyclic Chemistry, Volume IV, discusses the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry. Since the publication in 1963 of the first two volumes of this treatise, the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry, has proceeded apace. The importance of physical methods to structure determination and to the understanding of inter- and intramolecular interactions has increased no less than the flood of new work. Heterocyclic chemists are thus faced with the necessity of having more to comprehend for the efficient execution of their own work. The present volume includes chapters on electric dipole moments and heteroaromatic reactivity, which originally appeared in Volume I, and chapters on nuclear quadrupole resonance, nuclear magnetic resonance, and infrared spectra, which originally formed part of Volume II. Also included is one new topic: dielectric absorption.

Download or read book Phosphorus 31 NMR Spectroscopy written by Olaf Kühl and published by Springer Science & Business Media. This book was released on 2008-08-22 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.

Download or read book Heterocyclic Chemistry written by John A. Joule and published by John Wiley & Sons. This book was released on 2013-05-28 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has so closely matched the requirements of its readership over the years that it has become the first choice for chemists worldwide. Heterocyclic chemistry comprises at least half of all organic chemistry research worldwide. In particular, the vast majority of organic work done in the pharmaceutical and agrochemical industries is heterocyclic chemistry. The fifth edition of Heterocyclic Chemistry maintains the principal objective of earlier editions – to teach the fundamentals of heterocyclic reactivity and synthesis in a way that is understandable to second- and third-year undergraduate chemistry students. The inclusion of more advanced and current material also makes the book a valuable reference text for postgraduate taught courses, postgraduate researchers, and chemists at all levels working with heterocyclic compounds in industry. Fully updated and expanded to reflect important 21st century advances, the fifth edition of this classic text includes the following innovations: Extensive use of colour to highlight changes in structure and bonding during reactions Entirely new chapters on organometallic heterocyclic chemistry, heterocyclic natural products, especially in biochemical processes, and heterocycles in medicine New sections focusing on heterocyclic fluorine compounds, isotopically labeled heterocycles, and solid-phase chemistry, microwave heating and flow reactors in the heterocyclic context Essential teaching material in the early chapters is followed by short chapters throughout the text which capture the essence of heterocyclic reactivity in concise resumés suitable as introductions or summaries, for example for examination preparation. Detailed, systematic discussions cover the reactivity and synthesis of all the important heterocyclic systems. Original references and references to reviews are given throughout the text, vital for postgraduate teaching and for research scientists. Problems, divided into straightforward revision exercises, and more challenging questions (with solutions available online), help the reader to understand and apply the principles of heterocyclic reactivity and synthesis.
