Download or read book Contemporary Problems in Carbonium Ion Chemistry I II written by C. Rees and published by Springer. This book was released on 2013-11-27 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1965 a book by P. Bartlett appeared under the title "The Nonclassical Ions" 1). The book is a collection of papers reprinted from various journals. The many reviews that have appeared since 2-22) are either antiquated (the book published in 1972 12) covers the literature mainly before 1968) or relatively biased (e.g., 3.4,10» on brief 2, 7,11). This review attempts to discuss the various points of view on the "nonclassical" carbocations. The main point is to establish the relative role of "nonclassical" and "classical" ions in various chemical processes. The author has followed P. Bartlett's advice 1) that when setting forth the achievements of the human mind one should see how we came to the modern understanding of a given problem (" ... how we know what we know"). The theory of "nonclassical" ions offers an explanation of many unique chemical, stereochemical and kinetic peculiarities of bicyclic compounds. It has expanded our knowledge on chemical bonds in carbocations by introducing electron-deficient bonds (as in boron hydrides). It has accounted for many rearrangements of stable cations. As a "side" result our knowledge has been extended about ionization processes in a solution, as well as about stereochemical methods. 2 Main Terms of Nonclassical Carbocations In 1939 Hevell, Salas and Wilson 23) assumed an intermediate, "bridge" ion 2 to be formed when camphene hydrochloride 1 is rearranged into isobornyl chloride 3. This happened 17 years after Meerwein first postulated the intermediate formation of "carbonium" ions in chemical reactions.
Download or read book Boranes in Organic Chemistry written by Herbert C. Brown and published by Cornell University Press. This book was released on 2019-06-30 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The leading researcher in the uses of boranes in organic synthesis here reviews his work over the past thirty-five years, covering such areas as steric strains, the nonclassical ion problem, selective reductions, hydroboration, and the organoboranes as synthetic intermediates. But more than an exposition of enormous accomplishment, the book is a scientific autobiography that will provide chemists with historical perspective on their profession. The author's detailed narrative of his own research experiences not only adds to the understanding of the present state of the study of boranes, but will serve as a stimulus to imaginative research in the future.

Download or read book Atomic Clusters with Unusual Structure Bonding and Reactivity written by Pratim Kumar Chattaraj and published by Elsevier. This book was released on 2022-10-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic Clusters with Unusual Structure, Bonding and Reactivity: Theoretical Approaches, Computational Assessment and Applications reviews the latest computational tools and approaches available for accurately assessing the properties of a cluster, while also highlighting how such clusters can be adapted and utilized for the development of novel materials and applications. Sections provide an introduction to the computational methods used to obtain global minima for clusters and effectively analyze bonds, outline experimental approaches to produce clusters, discuss specific applications, and explore cluster reactivity and usage across a number of fields.Drawing on the knowledge of its expert editors and contributors, this book provides a detailed guide to ascertaining the stability, bonding and properties of atomic clusters. Atomic clusters, which exhibit unusual properties, offer huge potential as building blocks for new materials and novel applications, but understanding their properties, stability and bonding is essential in order to accurately understand, characterize and manipulate them for further use. Searching for the most stable geometry of a given cluster is difficult and becomes even more so for clusters of medium and large sizes, where the number of possible isomers sharply increase, hence this book provides a unique and comprehensive approach to the topic and available techniques and applications. - Introduces readers to the vast structural and bonding diversity that clusters show and reflects on their potential for novel application and material development - Highlights the latest computational methods and theoretical tools available for identification of the most stable isomers and accurate analysis of bonding in the clusters - Focuses on clusters which violate the rules established in traditional chemistry and exhibit unusual structure, bonding and reactivity
Download or read book Advances in Organometallic Chemistry written by and published by Academic Press. This book was released on 1994-04-22 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely acclaimed serial contains authoritative reviews that address all aspects of organometallic chemistry, a field which has expanded enormously since the publication of Volume 1 in 1964. Almost all branchesof chemistry now interface with organometallic chemistry-the study of compounds containing carbon-metal bonds. Organometallic compounds range from species that are so reactive that they only have a transient existence at ambient temperatures to those thatare thermally very stable. They are used extensively in the synthesis of useful compounds on both small and large scales. Industrial processes involving plastics, polymers, electronic materials, and pharmaceuticals all depend on advances in organometallic chemistry.In basic research, organometallics have contributed inter alia to: - Metal cluster chemistry - Surface chemistry - The stabilization of highly reactive species by metal coordination - Chiral synthesis - The formulation of multiple bonds between carbon and the other elements and between the elements themselves - Each volume of Advances in Organometallic Chemistry contains an index, and each chapter includes references
