This book was released on 2007-06-26 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.

Download or read book Activated Metals in Organic Synthesis written by P. Cintas and published by CRC Press. This book was released on 2020-01-29 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated Metals in Organic Synthesis discusses fundamental principles of the generation of activated, highly reactive metals, and their applications in organic synthesis. Following an introductory chapter on basic forms of metals the chapters in Part 1 are devoted to common strategies utilized for the preparation of active metals. These strategies include vaporization and subsequent co-condensation of metal atoms, in addition to depassivating methods employed commonly in laboratory syntheses. Chapters in Part 2 discuss relevant organic transformations in which metal activation plays a crucial role. Specific topics covered include metal-induced reductive methods; pinacolic, Reformatsky-, and Barbier-type reactions; McMurry ketone-olefin coupling; and the Bernet-Vasella reaction. Each chapter is followed by literature citations ranging from specific references to significant reviews. Many structural formulas are provided, making it easy to follow each synthesis. The book will be an important reference for students, organic chemists, and researchers in all areas of organometallic chemistry.

Download or read book Ion Radical Organic Chemistry written by Zory Vlad Todres and published by CRC Press. This book was released on 2008-10-20 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consolidating knowledge from a number of disciplines, Ion-Radical Organic Chemistry: Principles and Applications, Second Edition presents the recent changes that have occurred in the field since the publication of the first edition in 2003. This volume examines the formation, transformation, and application of ion-radicals in typical conditions of organic synthesis. Avoiding complex mathematics, the author explains the principles of ion-radical organic chemistry and presents an overview of organic ion-radical reactions. He reviews methods of determining ion-radical mechanisms and controlling ion-radical reactions. Wherever applicable, the text addresses issues relating to ecology and biomedical concerns as well as inorganic participants of the ion-radical organic reactions. After reviewing the nature of organic ion-radicals and their ground-state electronic structure, the book discusses their formation, the relationship between electronic structure and reactivity, mechanism and regulation of reactions, stereochemical aspects, synthetic opportunities, and practical applications. Additional topics include electronic and opto-electronic devices, organic magnets and conductors, lubricants, other materials, and reactions of industrial or biomedical importance. The book concludes by providing an outlook on possible future development in this field. Researchers and practitioners engaged in active work on synthetic or mechanistic organic chemistry and its practical applications will find this text to be invaluable in both its scope and its depth.
