Download or read book Aromaticity written by Israel Fernandez and published by Elsevier. This book was released on 2021-05-16 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluating the aromaticity of a molecular system and the influence of this concept on its properties is a crucial step in the development of novel aromatic systems. Modern computational methods can provide researchers with a high level of insight into such aromaticity, but identifying the most appropriate method for assessing a specific system can prove difficult. Aromaticity: Modern Computational Methods and Applications reviews the latest state-of-the-art computational methods in this field and discusses their applicability for evaluating the aromaticity of a system. In addition to covering aromaticity for typical organic molecules, this volume also explores systems possessing transition metals in their structures, macrocycles and even transition structures. The influence of the aromaticity on the properties of these species (including the structure, magnetic properties and reactivity) is highlighted, along with potential applications in fields including materials science and medicinal chemistry. Finally, the controversial and fuzzy nature of aromaticity as a concept is discussed, providing the basis for an updated and more comprehensive definition of this concept. Drawing on the knowledge of an international team of experts, Aromaticity: Modern Computational Methods and Applications is a unique guide for anyone researching, studying or applying principles of aromaticity in their work, from computational and organic chemists to pharmaceutical and materials scientists. Reviews a range of computational methods to assess the aromatic nature of different compounds, helping readers select the most useful tool for the system they are studying Presents a complete guide to the key concepts and fundamental principles of aromaticity Provides guidance on identifying which variables should be modified to tune the properties of an aromatic system for different potential applications

Besides various aspects of aromaticity one finds detailed discussions of homo-, spiroand hyperconjugation as well as effects of through-space and throughbond interactions. These effects are presented on the basis of experimental results and are analyzed by the use of qualitative arguments of perturbation theory and from a comparison with results from high level ab initio calculations. This book is a must-have for bachelor students from the second year on, master and PhD students of chemistry. Also students in science such as physics, biology and medicine will benefit from the concepts described in the book. Furthermore, chemists in research and development will be grateful to find here an overview of conjugation effects allowing to understand the structures, the dynamics and the reactivity of molecules.

Available in PDF, EPUB and Kindle. Book excerpt: Class-tested and thoughtfully designed for student engagement, Principles of Organic Chemistry provides the tools and foundations needed by students in a short course or one-semester class on the subject. This book does not dilute the material or rely on rote memorization. Rather, it focuses on the underlying principles in order to make accessible the science that underpins so much of our day-to-day lives, as well as present further study and practice in medical and scientific fields. This book provides context and structure for learning the fundamental principles of organic chemistry, enabling the reader to proceed from simple to complex examples in a systematic and logical way. Utilizing clear and consistently colored figures, Principles of Organic Chemistry begins by exploring the step-by-step processes (or mechanisms) by which reactions occur to create molecular structures. It then describes some of the many ways these reactions make new compounds, examined by functional groups and corresponding common reaction mechanisms. Throughout, this book includes biochemical and pharmaceutical examples with varying degrees of difficulty, with worked answers and without, as well as advanced topics in later chapters for optional coverage. Incorporates valuable and engaging applications of the content to biological and industrial uses Includes a wealth of useful figures and problems to support reader comprehension and study Provides a high quality chapter on stereochemistry as well as advanced topics such as synthetic polymers and spectroscopy for class customization
Download or read book Topological Approach to the Chemistry of Conjugated Molecules written by A. Graovac and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The second step is to determine constitution, Le. which atoms are bonded to which and by what types of bond. The result is ex pressed by a planar graph (or the corresponding connectivity mat rix) •••• In constitutional formulae, the atoms are represented by letters and the bonds by lines. They describe the topology of the molecule." VLADIMIR PRELOG, Nobel Lecture, December l2;h 1975. In the present notes we describe the topological approach to the che mistry of conjugated molecules using graph-theoretical concepts. Con jugatedstructures may be conveniently studied using planar and connec ted graphs because they reflect in the simple way the connectivity of their pi-centers. Connectivity is important topological property of a molecule which allows a conceptual qualitative understanding, via a non numerical analysis, of many chemical phenomena or at least that part of phenomenon which depends on topology. This would not be possible sole ly by means of numerical (molecular orbital) analysis.

Download or read book Hypervalent Iodine in Organic Synthesis written by A. Varvoglis and published by Academic Press. This book was released on 1996-11-14 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine. Each chapter deals with a particular iodine compound or families of compounds which have been used as reagents in a plethora of useful transformations. These include assorted oxidation, such as with the precious Dess-Martin reagent as well as with a wide range of further reactions. Prominent features of hypervalent iodine reagents derived from iodobenzene are: ready availability, operational simplicity, mild reaction conditions, and high efficiency. They are environmentally safe and can be recycled. New species may be easily prepared by introducing substituents in the benzene ring or changing the ligand attached to iodine. Their combination with other reagents broadens considerably their synthetic potential. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine reagents. Features up-to-date coverage of a wide range of topics Includes many tables featuring a diversity of reactivity, and a comprehensive index Acts as a comprehensive, up-to-date reference on all aspects of hypervalent iodine chemistry Contains a section on unusual efficiency of hypervalent iodine reactions
