Ring-Forming Polymerizations Pt B 2


Book Description

Ring-forming Polymerizations is a part of a volume that features a complete review and compilation of ring-forming polymerization reactions that result to heterocyclic ring formation. This book shows relevant growth in terms of research and commercial development in the area of polymer chemistry. This volume is comprised of four major chapters and is organized according to the specific heterocyclic ring structure resulting from ring-forming polymerizations. Each of the chapters is arranged further according to the polymer type and the different methods used in the preparation of that type, where emphasis is given to synthetic methods. This book specifically discusses the linear polymers that were intentionally made. Also, the structures presented are limited in scope considering that they are the result of the research cited in this book. However, claims that dispute a certain structure found in the research are also included to provide balance, fairness, and objectivity. Specifically, this book is a valuable resource for polymer and organic chemists. However, it can also be of great use to those scientists and researchers interested in the study of polymer chemistry of living systems.




Ring-Forming Polymerizations Pt B 1


Book Description

Ring-Forming Polymerizations, Part B, 1: Heterocyclic Rings presents a comprehensive review and compilation of ring-forming polymerization reactions that proceed with the formation of heterocyclic rings. Emphasis is placed on polymerizations leading to linear, high molecular weight products. This book is comprised of three chapters and begins with a discussion on polymerizations that result in the formation of a multiple bond containing at least one heteroatom. The condensation of amines with carbonyl compounds to yield poly(Schiff bases) and related polymers is examined, along with other carbon-nitrogen double bond-forming polymerizations. The next chapter is devoted to the polymerization of rings containing two carbon atoms, including the polymerization of polyphenols with diboronic acids and that of diisocyanides with triorganoborons. The last chapter describes the polymerization of rings containing three carbon atoms, with particular reference to polyisoxazoles and related polymers, polythiazoles, polyimidazoles and related polymers, polypyrazoles, and polytriazines. This monograph will be of interest to polymer and organic chemists and others who are concerned with the polymer chemistry of living systems.




Ring-Forming Polymerizations Pt A


Book Description

Ring-forming Polymerizations, Part A: Carbocyclic and Metallorganic Rings covers polymerization reactions that form carbocyclic rings and those that lead to metallorganic ring-containing structures. This book is organized into 11 chapters. The first four chapters describe ring-forming polymerizations that lead to the formation of homocyclic carbon-containing rings. These chapters specifically examine Diels-Alder polymerizations and certain diisopropenyl monomers polymerization yielding high molecular weight polyindanes. Chapter V is an introduction to polymers from metals and unsaturated carbon compounds, which has been called a ""natural coordination polymer"". Chapters VI to X deal with metallorganic ring polymers formed by chelation and are arranged according to the elements in the ligands that are affecting chelation. The final chapter explores ring forming polymerizations that yield polysiloxanes, polysilazanes, and certain polymetalloxanes. This book will be of value to organic chemists and researchers, as well as to organic chemistry teachers and students.

Oxidation in Organic Chemistry 5-B


Book Description

Organic Chemistry, Volume 5-B: Oxidation in Organic Chemistry, Part B presents some of the most common and significant reactions in organic chemistry, which involves oxidation and reduction. This book provides detailed discussions of specific oxidants or topics concerning oxidation of organic compounds. Organized into four chapters, this volume begins with an overview of the specific oxidants, including thallium(III), cupric ion, and ruthenium tetroxide. This text then presents the scope and preparative use as well as the mechanistic aspects of the various oxidations. Other chapters consider the significance of phenolic oxidative coupling in nature's biosynthetic pathways. This book discusses as well the various mechanistic alternatives for the enzymic and non-enzymic reactions, which will lead to a fuller understanding of the enzymic mechanisms and the greater synthetic utility of this reaction. The final chapter deals with the oxidative coupling of phenols. This book is a valuable resource for organic chemists and research workers.




Transition metal Organometallics In Organic Synthesis


Book Description

Transition Metal Organometallics in Organic Synthesis: Volume I reviews the literature in the field of organic synthesis with a focus on the most effective synthetic transformations. The text covers topics such as the general considerations in organic synthesis, C-C and C-X bond formations, and the isomerization and reorganization reactions of olefins. Also covered are topics such as displacement reactions with transition metal complexes, electrophilic reactions of organopalladium complexes, carbonylation reactions, and metal-carbene complexes — its structure, spectra, bonding, and direct synthesis. The book is recommended as a reference for chemists and inorganic chemists who would like to learn the applications of organometallic complexes as reagents and catalysts.




Total Synthesis of Steroids


Book Description

Organic Chemistry, Volume 30: Total Synthesis of Steroids provides an overall view of steroid total synthesis, including the general approaches, special problems, stereochemical complexities, expansion or contraction of rings, and insertion of hetero atoms. The book discusses the process of designing total syntheses; the biogenetic-like steroid synthesis, including cyclization of terminal epoxides as well as the total synthesis from nonepoxide precursors; and the synthesis of equilenin, estrone, bisdehydrodoisynolic acid, 18,19-bisnorprogesterone, 19-norpregnanes, and heterocyclic steroids. The text also describes the application of ABD intermediates in the Torgov synthesis; the synthesis of carbocyclics and thiasteroids; and the synthesis from p-anisylcyclohexanes and from C-5, C-8 bridged intermediates. The synthesis based on the type of reaction used in the condensation of the A fragment with the CD portion, as well as the methods of total synthesis in the preparation of 8-azasteroids and 8,13-diazasteroids are also considered. The book further tackles the synthesis of epiandrosterone, cortisone, aldosterone, 3ß-hydroxy-5a-pregnan-20-one, latifoline, conessine, and ring C aromatic steroids; the synthesis of trans-benzohydrindane derivatives and other common derivatives; and the synthesis of CD intermediates. Chemists, biochemists, and people involved in the study of steroid total syntheses will find the book invaluable.
