This book was released on 2023-05-25 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although carbon is considered the central element of organic chemistry, the broader chemical world has one more star player—oxygen. Billions of years of evolution have filled your room with oxygen as countless cyanobacteria and plants work on changing our planet. Oxygen is everywhere—from geology to biology, from the Earth's crust to the ozone layer. This digital primer aims to analyze chemical reactivity through the prism of oxygen chemistry. The key to understanding this chemistry is the lone pairs of oxygen (i.e., the underutilized "idle" electrons that do not directly contribute to the Lewis structure of molecules). By highlighting the many roles of oxygen, we will illustrate how chemistry rises above the limitations of Lewis structures and how electrons stay neither idle nor "lone" even if they are in "lone pairs" when an oxygen atom is near a reaction center. This digital primer will introduce important types of chemical bonding that transcend undergraduate textbooks but that are likely to drive the development of new chemical reactions in the future.

Download or read book Steric and Stereoelectronic Effects in Organic Chemistry written by Veejendra K. Yadav and published by Springer. This book was released on 2016-06-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The steric and stereoelectronic effects control the rate and stereochemical outcome of reactions. Hence, a decent understanding of the related concepts is essential for successful synthetic planning. The book attempts to address several important issues related to these concepts in a simplified manner, and is intended for graduate students. It lays stress on the important aspects of steric and stereoelectronic effects and their control on the conformational profile and reactivity features. The book covers the geometrical requirements for reactions at saturated and unsaturated carbons in both cyclic and acyclic systems, and the resultant stereochemical features. The aspect of geometrical flexibility is also covered with a few examples involving intramolecular reactions. It deals with the facial selectivity of nucleophilic additions to acyclic and cyclic carbonyl compounds, and explains how the steric and stereoelectronic effects control the same. The work comments on allylic strains and their stereochemical control on different reactions with the related conformational control. It is a must read to understand the control elements, the prominent among these elements are spiro-conjugation, periselectivity, torquoselectivity, a-effect, Hammett’s substituent constants, Hammond postulate, and Curtin-Hammett principle.

Available in PDF, EPUB and Kindle. Book excerpt: This widely-praised textbook is particularly suited for advanced undergraduates or graduates in chemistry, biochemistry, medicinal chemistry, and pharmacology. The third edition has been substantially revised to reflect new research in the field, and features a major new chapter on self-assembly, auto-organization, and molecular devices. The outstanding figures remain a highlight of the book, and were described in an earlier edition as "the best I've seen for showing the organic chemistry of biomolecules." (Quart. Rev. Biol.)

Download or read book Synthesis And Applications In Chemistry And Materials In 4 Volumes written by Armando J L Pombeiro and published by World Scientific. This book was released on 2024-01-16 with total page 2103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and Material Sciences naturally depend greatly on Synthesis as the initial stage for the existence of compounds and materials with desired behaviors, within the overall streamline of Design/Synthesis — Properties — Application/Function, and their relations. Such a general approach is of a too wide scope to be properly treated in a single set of publications, but this one on 'Synthesis and Applications in Chemistry and Materials' restricts itself by aiming to show the strength and international character of the current research in synthetic chemistry that is being developed in Portugal or abroad by teams that cooperate with this country. Hence, it gathers representative contributions of main Portuguese research groups and foreign collaborating ones. Nevertheless, the topic should be understood in a wide sense, being open to types of studies with significance on sustainable synthesis and applications in chemistry, materials and/or related sciences.

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.

Download or read book Advanced Organic Chemistry written by Francis A. Carey and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this edition is the same as that of the first edition, that is, to provide a deeper understanding of the structures of organic compounds and the mechanisms of organic reactions. The level is aimed at advanced undergraduates and beginning graduate students. Our goal is to solidify the student's understanding of basic concepts provided in an introduction to organic chemistry and to fill in much more information and detail, including quantitative information, than can be presented in the first course in organic chemistry. The first three chapters consider the fundamental topics of bonding theory, stereochemistry, and conformation. Chapter 4 discusses the techniques that are used to study and characterize reaction mechanisms. The remaining chapters consider basic reaction types with a broad coverage of substituent effects and stereochemistry being provided so that each reaction can be described in good, if not entirely complete, detail. The organization is very similar to the first edition with only a relative shift in emphasis having been made. The major change is the more general application of qualitative molecular orbital theory in presenting the structural basis of substituent and stereoelectronic effects. The primary research literature now uses molecular orbital approaches very widely, while resonance theory serves as the primary tool for explanation of structural and substituent effects at the introductory level. Our intention is to illustrate the use of both types of interpretation, with the goal of facilitating the student's ability to understand and apply the molecular orbital concepts now widely in use.
