Download or read book Phosphorus Ylides written by Oleg I. Kolodiazhnyi and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Wittig first developed and described phosphorus ylides, nobody could have imagined how useful and versatile this class of compounds could be. This book provides a comprehensive and up-to-date compilation of the chemistry and applications of phosphorus ylides in organic synthesis. The ylides are discussed as reagents in the synthesis of a broad range of substances, amongst them olefins, acetylenes, cyclic and heterocyclic compounds, in such naturally occurring compounds as pheromones, steroids and carotenoids, and pharmaceutically and biologically active compounds such as antibiotics and prostaglandins. A particularly beneficial feature of this book is the 150 key experimental procedures with all the necessary data, allowing the preparation to start immediately without the need for an extremely time-consuming literature search. But should a search prove inevitable, around 2,500 references provide easy access to the primary literature. Every chemist in academia and industry working in organic, bioorganic, inorganic, and medicinal chemistry will welcome this book as an inspiration of concepts, ideas and practical syntheses.
Download or read book Novel Sugar Phosphorus Ylides written by Nina Carole Sahabo and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Higher carbon chain sugars have gained increased interest recently; they are important building blocks of natural and unnatural products with biological properties. The synthesis of these higher sugar skeletons is commonly known to be achieved with the Wittig methodology which exploits phosphorus ylide chemistry. This method has been successfully used for the synthesis of the higher carbon sugars. The aim of this project was to synthesise ß, ß'-dioxo sugar-derived phosphorus ylides, a new class of ylides, as versatile intermediates to valuable higher carbon sugar derivatives and carbohydrate mimics. Model reactions were initially conducted; tetrahydro-2-furoic acid and tetrahydro-2H-pyran-4-carboxylic acid, compounds which are structurally similar to the precursor sugars, were identified as suitable model compounds. These compounds were converted to acyl chlorides and then converted to ß, ß'-dioxo phosphorus ylides precursors by acylation. The methodology proved successful and 8 examples were isolated. However, low yields were obtained due to the inevitable formation of triphenylphosphine oxide. The method was then extended to sugar derivatives, prepared using standard protecting group chemistry. It was found that acylation could be achieved using the simple acyl chloride route or peptide coupling methodology for sugar derivatives which were acid sensitive. ß, ß'-dioxo sugar-derived phosphorus ylides (16 examples) were successfully isolated in low yields. The oxidation and thermal reactivity of the ß, ß'-dioxo ylides were studied. Oxidation resulted in the successful synthesis of vicinal tricarbonyls, isolated as a mixture with the gem-diols (hydrates). The thermal decomposition of the ylides gave alkynes in moderate yields.

Download or read book Organophosphorus Reagents written by Dr. Patrick J. Murphy and published by Practical Approach in Chemistr. This book was released on 2004 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organophosphorus Chemistry: A Practical Approach in Chemistry provides a practical introduction to the field by mixing a brief review of the subject area with key experimental details and sample procedures. Phosphorus is an element that has been central to the development of our modern way of life. Its chemistry plays a key role in the development of such important areas as pharmaceuticals, agrochemicals, modern materials and molecular biology. Much of this work requires a sound understanding of the organic chemistry of phosphorus and this volume is designed to instruct the reader in the essential methodology used. Topics covered include phosphines, applications of phosphorus (III) and (V) compounds as reagents in synthesis, the chemistry of phosphorus ylides, applications of the Wittig reaction in the synthesis of heterocyclic and carbocyclic compounds, preparation of Iminophosphoranes and their synthetic applications in the aza-Wittig reaction, phospho-transfer processes leading to [P-C] bond formation, low valent phosphorus compounds and phosphorus methods in oligonucleotide chemistry. It is intended not only for the specialist in organophosphorus chemistry, but also for the organic chemist with little experience in the field who wishes to add phophorus-based techniques to his or her ensemble of synthetic methods.
Download or read book Phosphorus III Ligands in Homogeneous Catalysis written by Paul C. J. Kamer and published by John Wiley & Sons. This book was released on 2012-05-09 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 60 years the increasing knowledge of transition metal chemistry has resulted in an enormous advance of homogeneous catalysis as an essential tool in both academic and industrial fields. Remarkably, phosphorus(III) donor ligands have played an important role in several of the acknowledged catalytic reactions. The positive effects of phosphine ligands in transition metal homogeneous catalysis have contributed largely to the evolution of the field into an indispensable tool in organic synthesis and the industrial production of chemicals. This book aims to address the design and synthesis of a comprehensive compilation of P(III) ligands for homogeneous catalysis. It not only focuses on the well-known traditional ligands that have been explored by catalysis researchers, but also includes promising ligand types that have traditionally been ignored mainly because of their challenging synthesis. Topics covered include ligand effects in homogeneous catalysis and rational catalyst design, P-stereogenic ligands, calixarenes, supramolecular approaches, solid phase synthesis, biological approaches, and solubility and separation. Ligand families covered in this book include phosphine, diphosphine, phosphite, diphosphite, phosphoramidite, phosphonite, phosphinite, phosphole, phosphinine, phosphinidenene, phosphaalkenes, phosphaalkynes, P-chiral ligands, and cage ligands. Each ligand class is accompanied by detailed and reliable synthetic procedures. Often the rate limiting step in the application of ligands in catalysis is the synthesis of the ligands themselves, which can often be very challenging and time consuming. This book will provide helpful advice as to the accessibility of ligands as well as their synthesis, thereby allowing researchers to make a more informed choice. Phosphorus(III) Ligands in Homogeneous Catalysis: Design and Synthesis is an essential overview of this important class of catalysts for academic and industrial researchers working in catalyst development, organometallic and synthetic chemistry.

Book excerpt: Organic Chemistry, Volume 7: Ylid Chemistry focuses on the physical and chemical properties of ylids. This book discusses the Wittig synthesis of olefins, which involves the reaction between carbonyl compounds and phosphonium ylids. Organized into two parts encompassing nine chapters, this book starts with an overview of the definition of ylids as a substance in which a carbanion is attached directly to a heteroatom transporting a high degree of positive charge. This text then examines the unique stabilization that afforded the carbanions by the presence of the adjacent 'onium atom group, which is the special characteristic of ylids. Other chapters consider the general structure of phosphonium ylids, which virtually has no limitation on the nature of the X groups on phosphorus. This book discusses as well the Wittig reaction involving a condensation-elimination between a phosphonium ylid and ketone. The final chapter deals with the various aspects of the chemistry of sulfur ylids. This book is a valuable resource for chemists.
