Polymers and Pyridazines by Péter Tétényi Pdf

In the past few years, a few articles have been published on the solid-phase synthesis of pyridazine derivatives. These methods apply to intermediates weakly bound to polymers, as a result of which the ester bond is cleaved easily, either during ring closure or right after it. There are few polymer-supported syntheses of heterocycles. This book, Polymers and Pyridazines, discusses a new strategy for polymer-supported synthesis of pyridazine derivatives with much higher reaction rates, applying higher loading and much wider reaction conditions due to the more stable attachment. On the basis of the research conducted, a fundamental break-through was achieved in solid-phase heterocyclic chemistry. The experiments are accompanied by colored drawings and 3D diagrams to help understand the importance of swelling and/or excess concentrations of reagents. Detailed experiments provide complete procedures with infrared difference spectra. The book will be a helpful reference for academy polymer specialists and postgraduate students studying polymer syntheses of general substrates.

Polymers as Aids in Organic Chemistry by N.K Mather,C. K. Narang,Ross Ernest Williams Pdf

Polymers as Aids in Organic Chemistry covers the broad classifications and application of polymers in organic chemistry. This book is organized into 15 chapters that focus on the transformation of polymers and their role in other reagents that must be easily separated from their final product. After a brief introduction to polymer chemistry, the book presents a tabulation of the various types of polymers that have been used and the methods for their characterization. It then discusses the use of polymers as supports in peptide, oligonucleotide, and oligosaccharide chemistry; in peptide sequencing; in monofunctionalized difunctional compounds preparation, as aids in asymmetric syntheses; and as trapping agents in the determination of reaction intermediates. The subsequent chapters describe the use of polymers as catalysts, with particular emphasis on transition metals immobilized in the polymer matrix and used as catalysts. The concluding chapters examine polymer-immobilized compounds, enzymes, and whole cells that have been used to carry out a large number of reaction, most of which impinge on the area of organic chemistry. Polymer scientists and researchers and organic chemists will find this book invaluable.

Fluorine in Heterocyclic Chemistry Volume 2 by Valentine Nenajdenko Pdf

This two-volume work combines comprehensive information on the chemistry of the fluorinated heterocycles. The material has been divided such that the first volume is dedicated to 5-membered fluorinated heterocycles and macrocycles, while the second volume combines data connected with the chemistry of fluorine containing 6-membered heterocycles. Both volumes will be of interest to synthetic organic chemists in general, and particularly for those colleagues working in the fields of heterocyclic-compound chemistry, materials chemistry, medicinal chemistry, and fluorine chemistry. All information is presented and classified clearly to be effective source for broad auditory of chemists. It will be interesting for scientists working in the field of inorganic and coordination chemistry. Fluorinated heterocycles are becoming increasingly important in many areas including the pharmaceutical industry, materials science and agriculture. The presence of fluorine can result in substantial functional changes in the biological as well as physicochemical properties of organic compounds. Incorporation of fluorine into drug molecules can greatly affect their physicochemical properties, such as bond strength, lipophilicity, bioavailability, conformation, electrostatic potential, dipole moment, pKa etc. as well as pharmacokinetic properties, such as tissue distribution, rate of metabolism and pharmacological properties, such as pharmacodynamics and toxicology.
