Available in PDF, EPUB and Kindle. Book excerpt: The renowned Oxford Chemistry Primer series, which provides focused introductions to a range of important topics in chemistry, has been refreshed and updated to suit the needs of today's students, lecturers, and postgraduate researchers. The rigorous, yet accessible, treatment of each subjectarea is ideal for those wanting a primer in a given topic to prepare them for more advanced study or research. Moreover, cutting-edge examples and applications throughout the texts show the relevance of the chemistry being described to current research and industry.Learning features provided in the primers, including questions at the end of every chapter and interactive online MCQs, encourage active learning and promote understanding. Furthermore, frequent diagrams, margin notes, further reading, and glossary definitions all help to enhance a student'sunderstanding of these essential areas of chemistry.Pericyclic reactions constitute a major strand of organic chemistry, including such commercially important synthetic reactions as the Diels-Alder reaction. Reactions such as these are characterised by their predictable stereochemistry and cyclic transition structures. This primer reviews thesereactions, explaining their theoretical basis via correlation diagrams, and showing students how to recognise the different types of pericyclic reaction, their mechanisms, and applications to organic synthesis.

Download or read book The Conservation of Orbital Symmetry written by R. B. Woodward and published by Elsevier. This book was released on 2013-10-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conservation of Orbital Symmetry examines the principle of conservation of orbital symmetry and its use. The central content of the principle was that reactions occur readily when there is congruence between orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence does not obtain—or to put it more succinctly, orbital symmetry is conserved in concerted reaction. This principle is expected to endure, whatever the language in which it may be couched, or whatever greater precision may be developed in its application and extension. The book opens with a review of the elementary aspects of the molecular orbital theory of bonding. This is followed by separate chapters on correlation diagrams, the conservation of orbital symmetry, theory of electrocyclic reactions, theory of cycloadditions and cycloreversions, and theory of sigmatropic reactions. Subsequent chapters deal with group transfers and eliminations; secondary conformational effects in concerted cycloaddition reactions; and generalized selection rules for pericyclic reactions.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise introduction to pericyclic and photochemical reactions for organic synthesis. In the first part about pericyclic reactions, the author explains electrocyclic reactions, cycloaddition reactions, sigmatropic rearrangements, and group transfer reactions. The second part on photochemistry is dedicated to photochemical reactions of a variety of compound classes, including alkenes, dienes, and polyenes, carbonyl compounds, and aromatic compounds. Additionally, photofragmentation reactions are described in a dedicated chapter. The last chapter gives an outlook on applications of photochemistry and natural photochemical phenomena. Both parts start with a comprehensive presentation of the general principles of the pericyclic and photochemical reactions. All chapters are rich in examples, which help illustrate the explained principles and establish ties to results and trends in recent research. Additionally, each chapter offers exercises for students, and solutions to the problems are provided in a separate appendix. This book nicely illustrates the utility of pericyclic and photochemical reactions and provides students and researchers with the tools to apply them routinely for an efficient synthesis of complex organic molecules. It will therefore appeal to advanced undergraduate students, graduate and postgraduate students, and even to practitioners and scientists in the field of organic synthesis. The rich examples and exercises will also make it a versatile tool for teachers and lecturers.

Download or read book Cycloaddition Reactions in Organic Synthesis written by Shu Kobayashi and published by John Wiley & Sons. This book was released on 2002 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the miners' strike in the 1980s, a worker is killed in the striking coalfields of Wales. Some months later, a government minister thought to be connected with the death is also shot. Lewis Redfern—once a radical but now a political analyst and journalist—pursues the sniper, a lonely hunt that leads him through an imbroglio of civil service leaks to a secret organization: a source of insurrection far more powerful than anyone could have suspected known as the Volunteers. In this fast-paced narrative of espionage and intrigue, Redfern, through his obsessive pursuit of justice, finally encounters the truth about himself as the novel discusses the conflict between moral choice and political loyalty.
Download or read book Pericyclic Reactions in Organic Synthesis written by Julia Mae Robinson-Surry and published by . This book was released on 2011 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I of this thesis describes a formal, metal-free, [2 + 2 + 2] cycloaddition strategy based on a cascade of two pericyclic processes. An intramolecular propargylic ene reaction of a 1,6-diyne is used to generate a vinylallene, which then reacts in an inter- or intramolecular Diels-Alder reaction with an alkenyl or alkynyl dienophile. Reactions involving unsymmetrical alkenyl and alkynyl dienophiles proceed with good to excellent regioselectivity, and endo products are formed exclusively. The mechanism of several earlier fully intramolecular related transformations have been shown to involve an analogous process rather than the diradicalmediated pathways proposed previously. Part II of this thesis describes a [4 + 4] annulation strategy involving the intramolecular [4 + 2] cycloaddition of conjugated enynes with activated cyclobutene derivatives to access intermediates containing bicyclo[4.2.0]-2,4-octadiene moieties that then undergo electrocyclic ring opening reactions to provide 1,3,5-cyclooctatrienes. Five novel cyclooctatrienes have been prepared using this method. Part III of this thesis describes the use of supercritical carbon dioxide as an environmentally friendly alternative to conventional solvents for the synthesis of a variety of carboxylic amides. The addition of amines to ketenes generated in situ via the retro-ene reaction of alkynyl ethers provides amides in good yield, in many cases with ethylene as the only byproduct of the reaction. With the exception of primary, unbranched amines, potential side reactions involving addition of the amines to carbon dioxide are not competitive with the desired C-N bond-forming reaction. The amide synthesis is applicable to the preparation of p-hydroxy and P-amino amide derivatives, as well as amides bearing isolated carbon-carbon double bonds.
