Book excerpt: During the last 30 years, knowledge of the essential role that pyrrole structures play in the chemistry of living organisms, drug design, and the development of advanced materials has increased. Correspondingly, research on the diverse issues of synthetic, theoretical, and applied chemistry has snowballed. Devoted to the latest achievements of this field, Chemistry of Pyrroles covers the discovery and development of a novel, facile, and highly effective method for the construction of the pyrrole ring from ketones (ketoximes) and acetylene in superbase catalytic systems (Trofimov reaction). It provides cutting-edge details on the preparation of valuable but previously inaccessible pyrrole compounds. It includes approximately 1,000 structures of novel pyrrole compounds, their yields, and physical-chemical characteristics. The authors analyze conditions of typical syntheses, limitations of their applicability, and possibility of vinyl chloride or dichloroethane application instead of acetylene. They examine chemical engineering aspects of the first synthesis of tetrahydroindole and indole from commercially available oxime of cyclohexanone and acetylene. In addition, the book discusses new facets of pyrroles and N-vinyl pyrroles reactivity in the reactions with the participation of both the pyrrole ring and N-vinyl groups. The book provides condensed, clear-cut information on novel syntheses of substituted pyrroles as key structural units of living matter (chlorophyll and hemoglobin), pharmaceuticals, and monomers for optoelectronic materials. It includes tables that provide references to original works, forming a guide to a variety of the reactions and synthesized compounds discussed. With coverage of the broad range of pyrrole chemistry and methods for their synthesis, it provides both a theoretical and an experimental basis for drug design.
Download or read book The Chemistry of Pyrroles written by R. Alan Jones and published by Academic Press. This book was released on 2013-10-22 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Pyrroles, Volume 34 aims to provide a comprehensive survey of the synthesis of simple pyrroles and to present, wherever possible, a mechanistic and theoretical rationale for the multitude of reactions known for pyrroles. The book discusses the structure and reactivity of pyrrole; the synthesis of the pyrrole ring; and the electrophilic substitution of the pyrrole ring. The text also describes the oxidation and reduction of the pyrrole ring; the rearrangement and addition reactions; and the ketones, aldehydes, and carboxylic acid derivatives of pyrrole. Alkylpyrroles and related compounds; hydroxy- and aminopyrroles and related compounds; and azafulvenes are also considered. The book further tackles the physico-organic properties of pyrrole. Chemists and researchers of pyrrole chemistry will find the text invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: "A review of the chemical literature has shown that electro-organic methods compare favorably with purely chemical methods for certain syntheses belonging to the following general classes of reactions: coupling, oxidation, reactions with halogens, and reductions. Electro-organic methods have been used most successfully in synthesis by reduction. The chief advantage is using electrolytic reduction in preference to a chemical one is that it offers a more exact control of conditions, and consequently should give a higher yield and a purer product. The advantages of the means of reduction suggested an investigation of its use in the synthesis of hydrogenated products of pyrrole, and unsaturated heterocyclic ring compound. Two possible reduction products might results; a 2-5 dihydro pyrrole (pyrroline), and a tetra hydropyrrole (pyrrolidine), both of which are known and have been characterized. They have been produced by chemical and catalytic reduction in low yields from pyrrole. The variable conditions to be studied in this investigation will include composition of the catholyte, cathode material, current density, time of electrolysis and temperature"--Introduction, leaf 1.
Download or read book Pyrroles Volume 48 Part 1 written by Richard A. Jones and published by John Wiley & Sons. This book was released on 2009-09-17 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.

Book excerpt: Pyrrole: Synthesis and Applications provides an overview of polypyrrole synthesis by different methods such as chemical polymerization, lecetro-polymerization, photo-initiated polymerization and γ irradiated polymerization.Pyrrole derivatives play a crucial role in organic chemistry, medicinal chemistry, and heterocyclic chemistry. Pyrrole scaffold is extensively used in the synthesis of drug molecules with various pharmacological properties, as well as in material sciences.Finally, the authors review studies on the electrical properties of hybrid polymers which revealed that their electrical conductivity increased markedly with the proportion of pyrrole in the initial mixture. This is attributed to the formation of an electrically conducting polymer network in the non-conducting methacrylate matrix.

Available in PDF, EPUB and Kindle. Book excerpt: Catalytic Hydrogenation over Platinum Metals focuses on catalytic hydrogenation as an effective process in attaining controlled transformations of organic compounds. Composed of contributions of various authors, the book first provides information on catalysts, equipment, and conditions. Catalyst stability and reuse; types of catalyst; platinum metals; and synergism are covered. The text proceeds with discussions on hydrogenation reactors. Topics include atmospheric pressure reactors; low pressure reactors; microreactors; and high pressure reactors. The book also covers hydrogenation of carbon-carbon unsaturation. Catalytic metal; modified catalyst systems; stereochemistry; diacetylenes; and hydrogenolysis are discussed. The text also looks at the hydrogenation of aromatics, nitrogen and carbonyl compounds, and hydrogenolysis. Numerical representations and analysis, diagrams, and reactions of compounds when exposed to different laboratory conditions are considered. The selection is a great source of data for readers interested in studying the process of catalytic hydrogenation.
Download or read book Reduction written by Barry M. Trost and published by Elsevier. This book was released on 1992-09-08 with total page 1166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains 37 chapters on methods for reducing functional groups, organized into four main parts. (i) Reduction of C=X systems, where X is an electronegative heteroatom, divided into 14 chapters based on the degree of reduction, the oxidation level of the C=X substrate, and on the nature of the reagent. (ii) Reduction of X=Y systems, divided into three chapters, covering the reduction of such groups as nitro, azo, and the various kinds of P=O and S=O groups. (iii) Reduction of C=C and C≡C, divided into 12 chapters based on the method of reduction, with aromatic, heteroaromatic, and conjugated systems treated separately, and including an extensive discussion of hydrometallation. (iv) Reduction of single bonds, C-X to C-H, in eight chapters, including the hydrogenolysis of the various kinds of C-X bonds, the reduction of epoxides, and the reduction of vinyl derivatives to alkenes. Each chapter includes a discussion of chemoselectivity, regioselectivity, and stereoselectivity, wherever it is appropriate, and most include advice on the reagent of choice, and the mechanistic basis of the various methods of reduction. In short, it is, within the space available, as near to a comprehensive account of reduction in organic chemistry as one could hope for.
