Book Description
Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
Phosphorus chemistry is a diverse field and this volume focuses on new developments of "old themes" with different approaches and ideas, state of the art for two topics of general interest, and the emerging fields of research. This volume only describes in part the huge number of original papers on phosphorus-related topics.

Book Description
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.

Book Description
Alexander Todd, the 1957 Nobel laureate in chemistry is credited with the statement: “where there is life, there is phosphorus”. Phosphorus chemical biology underlies most of life’s reactions and processes, from the covalent bonds that hold RNA and DNA together, to the making and spending 75 kg of ATP every day, required to run almost all metabolic and mechanical events in cells. Authored by a renowned biochemist, The Chemical Biology of Phosphorus provides an in-depth, unifying chemical approach to the logic and reactivity of inorganic phosphate and its three major derivatives (anhydrides, mono- and diesters) throughout biology to examine why life depends on phosphorus. Covering the breadth of phosphorus chemistry in biology, this book is ideal for biochemistry students, postgraduates and researchers interested in the chemical logic of phosphate metabolites, energy generation, biopolymer accumulation and phosphoproteomics.

Book Description
Pergamon Texts in Inorganic Chemistry, Volume 3: The Chemistry of Phosphorus focuses on the physical and chemical properties of phosphorus. This book discusses phosphorus compounds, such as phosphorus hydrides and phosphonium compounds; phosphorus halides and phosphorus pseudohalides; thiophosphoryl halides and thiophosphoryl pseudohalides; phosphorus oxides; and phosphorus-nitrogen compounds. The pyrophosphates, tripolyphosphates, polyphosphates, cyclic metaphosphates, and ultraphosphates are also covered in this text. This publication is intended for chemical engineering students and chemists researching on the characteristics of phosphorus.

Book Description
Provides a high level reference source for scientists engaged in any aspect of plant research − chemistry, biochemistry or physiology − with primary focus on the chemistry of phosphorus-containing compounds that occur naturally in the plant kingdom, and specifically in the higher plants (Plantae). The book is comprehensive with respect to nomenclature, physical properties, and distribution worldwide. There are many tables of actual data on phosphorus compounds occurring in whole plants and parts of plants. The tables provide detailed data that is needed by the food industry, agriculture, etc as many of the phosphorus compounds are common to both plants and animals. Two appendices cover other aspects including changes in phosphorus-containing compounds during germination and their accumulation during growth and senescence. The final sections of the book comprise separate indexes of plants, compounds and authors. Comprehensive examination of phosphorus compounds found in plants Extensive tables listing types of compounds and their occurrence in plants including: Nomenclature; Occurrence; Physical Properties; Synthesis; Hydrolysis; Phosphorylation; Extraction; Separation and Analysis Easy to use indexes of plants, compounds and authors
