DOWNLOAD EBOOKThis work deals with phosphorus compounds that have double or triple bonds to another main group element, & also includes R-P fragments (phosphinidenes). It is concerned with a current trend that has developed over the last 25 years which has almost completely overturned the covalent bond rule. Specialist journals have often been excessive in their interest of this trend. The authors aim to present the whole field of 'low coordination' phosphorus chemistry in a series of specialized chapters, & to stimulate interest in future fields of research.

DOWNLOAD EBOOKIn the first work to comprehensively cover this all-important topic, the recognized expert Helmut Vorbrüggen provides both organic and bioorganic chemists with much new and valuable information for preparative synthesis. Although every organic chemist may be familiar with different aspects of silylation for the protection of functional groups, this book covers the concept of protection while simultaneously silylating-activating various functional groups, such as amides and ureas. This novel methodology opens thus numerous synthetic pathways while effecting the elimination of water in it volatile persilylated form under rather mild reaction conditions, which are often advantageous compared to conventional methods. The compact form and clear structure of this monograph make this a long-awaited ready reference. From the contents: Introduction * Techniques of Preparative Silylations-Desilylations * Preparation and Properties of Siliconoxy-Leaving Groups * Reactions of Free and Derivatized Carboxylic Acids and Carbon Dioxide * Reactions of Aldehydes and Ketones * Reactions of Alcohols, Ethers and Epoxides * Reaction of N-O Systems * Reactions of S-O and Se-O Systems * Cyclizations and Ring Enlargements * Base and Acid-Catalyzed as well as Thermal Eliminations of Trimethylsilanol. Peterson Reactions * Formation of Carbon-Phosphorous Double- and Triple Bonds * Reductions and Oxidations * Dehydration-Activation as well as Silylation of Inorganic and Organic Salts and Metalorganic Compounds * Formation of Polymers

DOWNLOAD EBOOKUndoubtedly 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.

DOWNLOAD EBOOKStrong 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.

DOWNLOAD EBOOKComprehensive 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
