DOWNLOAD EBOOKThis volume C 1 is the first supplement volume to "Phosphor" C which was published in 1965 and covers the compounds of phosphorus. Starting with the binary species formed between phosphorus and hydrogen, the present volume deals with the neutral mononuclear compounds PH through PH ; the ions featuring the same stoichiometric composition are s covered in separate sections. PH and PH are the major initial gaseous decomposition products of PH and, thus, also 2 J intermediates in many of its gas-phase reactions. Both molecules and their ions have been thoroughly investigated by a variety of modern, high-resolution spectroscopic methods during the last three decades. The coverage of their physical, and mostly molecular, properties re presents the largest part of the first two chapters (PH and ions pp. 2 to 47; PH and ions pp. 47 2 to 111). PH is the only compound described in this volume which is thermally stable under normal J conditions. It is the phosphorus analog of ammonia, but exhibits, however, a quite different chemical behavior towards most elements and compounds. The majority of its physical, and in particular spectroscopic, properties have been determined in great detail since the sixties, partially in regard to spectroscopic investigations of the atmospheres of the outer planets.

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 EBOOKSilicon in Organic Synthesis provides an introduction to the organic chemistry of silicon. This book places particular emphasis on the concept of silicon as a "ferryman, mediating the transformation of one wholly organic molecule into another. The book begins by reviewing the discovery and development of organosilicon compounds. This is followed by separate chapters on the physical properties of organosilicon compounds; the preparation of a-metallated organosilanes, which play a key role in preparative organosilicon chemistry; migration/rearrangement reactions of silicon; the preparation and chemistry of vinylsilanes, allylsilanes, arylsilanes, and organosilyl metallic compounds. Subsequent chapters cover the synthesis of compounds such as alkene, alkynylsilanes, allenylsilanes, silylketenes, alkyl silyl ethers, acyloxysilanes, and silyl enol ethers. This book aims to serve as a timely introduction to organic chemistry for students and practitioners of synthetic organic chemistry, as well as provide a source of useful information and possibly of new ideas to those already experienced in the area.

DOWNLOAD EBOOKNuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.

DOWNLOAD EBOOKPhosphorus: The Carbon Copy examines the extraordinary similarity between low coordinate phosphorus compounds and unsaturated carbon compounds. Written by three of the leading researchers in the field of modern phosphorus chemistry, Phosphorus: The Carbon Copy focuses on the interface between phosphorus and the transition metal elements and deals with the most recent aspects of unsaturated organophosphorus compounds and their coordination chemistry. Aimed at graduate students as well as academic and industrial researchers, this concise volume publicisies the extraordinary potential of these new phosphorus compounds for applications in catalysis, molecular materials and biochemistry.
