This book was released on 2002 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong non-ionic bases are highly advantageous as stoichiometric reagents and as catalysts in synthetic organic chemistry owing to side reactions that f- quently occur when ionic bases such as LDA or alkali metal alkoxides are employed. A second reason that non-ionic bases are frequently more useful in these applications is that such bases are often more soluble in less polar organic solvents, particularly at low temperatures. Thirdly, non-ionic bases can provide reactive naked or tightly associated deprotonated substrate anions that are s- bilized by the relatively large, poorly solvated cations formed by the protonated base. In such cations, extensive positive charge delocalization can occur. Prior to our work on pro-azaphosphatranes of type 1 (Scheme 1), the very strong n- ionic bases utilized for organic transformations were largely confined to the nitrogenous bases shown below (Scheme 2). Scheme 1 Scheme 2 4 J.G. Verkade 2 Uses of Strong Nonionic Nitrogen Bases 2. 1 Amines One of the earliest strong non-ionic bases to make its appearance was Proton Sponge and its derivatives [1] and these systems have been reviewed [2]. More recently Proton Sponge has been used in the palladium-catalyzed arylation of 2,3-dihydrofuran [3], and it also catalyzes Knoevenagel condensations of s- strates possessing activated methylene groups [4]. Recently the synthesis of the macrocyclic tetramine below (Scheme 3) was reported [5]. The encrypted nitrogens are very basic (pK,24.

Available in PDF, EPUB and Kindle. Book excerpt: Undoubtedly the chemistry of phosphorus appears more and more attractive in the sense that phosphorus presents an extraordinary versatile behaviour that allows the synthesis of a large number of different phosphorus reagents usable for applications in different fields, from biology to material science without f- getting key applications in catalysis. The full maturity of this topic of research can be explained by all the acquired knowledge over these twenty last years. Organic and inorganic chemistries of P , P and P species have been the s- in ]V v ject of thousands of publications while the chemistry of low coordinated ph- phorus derivatives experienced its hour of glory from the 1970s to the early 1990s. In parallel, interactions between phosphorus compounds and transition metals afforded many complexes, a lot of which present fascinating properties as catalysts. The interest in all these themes really is not decreasing, indeed some fas- nating areas of research are emerging or are the subject of many investigations: the medicinal chemistry of bisphosphonates, the role of phosphorus in biology, phosphorus ligands in radiopharmaceutical chemistry, phosphorus in material science, new polymers and dendrimers incorporating phosphorus, and as- metric catalysis to name but a few. Indeed researchers, benefitting from their background in basic phosphorus chemistry are developing many new fields of research.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to open new fields of interest in phosphate chemistry and to suggest a new system of classification for phosphates. Due to the very rapid development of this branch of chemistry during the last thirty years and the very confusing nomenclature often used in chemical literature, this first attempt seems not only justified but necessary. The suggested classification is not revolutionary, with respect to condensed phosphates for instance, but establishes clear boundaries between some categories of compounds such as adducts and heteropolyanion-compounds. The first chapters cover the present state of phosphate chemistry in a general way and could serve as an introduction to phosphates for some categories of students or teachers. The next few chapters are devoted to more specialized topics which would be of interest to chemists, crystallographers or solid-state specialists.Some specific aspects of the crystal chemistry of phosphates, such as the geometry of the networks built by acidic phosphoric anions, for instance, are covered for the first time. The final chapter suggests some improvements for the present system of classification for phosphates.In addition, presented for the first time are the results recently obtained for the replacement of asbestos by harmless biodegradable phosphate fibers.

Download or read book Comprehensive Inorganic Chemistry II written by and published by Newnes. This book was released on 2013-07-23 with total page 7694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
