    A giant in the field and at times a polarizing figure, F. Albert Cotton’s contributions to inorganic chemistry and the area of transitions metals are substantial and undeniable. In his own words, My Life in the Golden Age of Chemistry: More Fun than Fun describes the late chemist’s early life and college years in Philadelphia, his graduate training and research contributions at Harvard with Geoffrey Wilkinson, and his academic career from becoming the youngest ever full professor at MIT (aged 31) to his extensive time at Texas A&M. Professor Cotton’s autobiography offers his unique perspective on the advances he and his contemporaries achieved through one of the most prolific times in modern inorganic chemistry, in research on the then-emerging field of organometallic chemistry, metallocenes, multiple bonding between transition metal atoms, NMR and ESR spectroscopy, hapticity, and more. Working during a time of generous government funding of science and strong sponsorship for good research, Professor Cotton’s experience and observations provide insight into this prolific and exciting period of chemistry.

    • Michael Harmata
    • Inglés
    A classic in the area of organic synthesis, Strategies and Tactics in Organic Synthesis provides a forum for investigators to discuss their approach to the science and art of organic synthesis. Rather than a simple presentation of data or a secondhand analysis, we are given stories that vividly demonstrate the power of the human endeavor known as organic synthesis and the creativity and tenacity of its practitioners. Firsthand accounts of each project tell of the excitement of conception, the frustration of failure and the joy experienced when either rational thought or good fortune gives rise to the successful completion of a project. This book series shows how synthesis is really done, and we are educated, challenged and inspired by these accounts, which portray the idea that triumphs do not come without challenges. We also learn that we can meet challenges to further advance the science and art of organic synthesis, driving it forward to meet the demands of society, in discovering new reactions, creating new designs and building molecules with atom and step economies that provide solutions through function to create a better world.

    Microwave-Assisted Sample Preparation for Trace Element Analysis describes the principles, equipment, and applications involved in sample preparation with microwaves for trace element analysis. The book covers well-established applications as well as new trends in this field. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. The use of microwaves in sample preparation has increased in recent decades. Several applications of microwaves for sample preparation can be found in the literature for practically all types of sample matrices, especially for the determination of trace elements by atomic spectrometric techniques, safely and cleanly reducing the time involved in this step. Microwave-assisted sample preparation is not only a tool for research but also for routine analysis laboratories; the state-of-the-art in sample preparation in trace element analysis. This book is the only resource for chemists specifically focused on this topic.

    • Inglés
    The Isoquinoline Alkaloids: A Course in Organic Chemistry is a description of the chemical structures of alkaloids. The book discusses the processes for degradation of isoquinoline alkaloids to recognizable compounds such as oxidation and exhaustive methylation. The associated processes in removing the nitrogen atom are also explained. The commonly used Hofmann process and the interpretation of its result are evaluated in the degradation of alkaloids. The cactus ""pellote"" used by Mexican Indians to induce hallucinatory experiences is examined. The active ingredient is identified as mescaline; its composition is analyzed to contain one primary amino and three methoxyl groups. The different syntheses made to duplicate mescaline are described. The structures of morphine, codeine, and thebain, which are all alkaloids of opium, are also analyzed. Another example of a principal alkaloid found in a plant is emetine found in the root of the ipecac. The pharmacological bases of emetine are isolated and noted as emetamine, cephaeline, psychotrine, and O-methylpsychotrine. The text also traces many other structural relationships within the subgroups of the isoquinoline alkaloids. Chemists, students and professors in organic chemistry, and laboratory technicians whose work is related to pharmacology will find this book informative.

    • Inglés
    Organic Chemistry Concepts and Applications for Medicinal Chemistry provides a valuable refresher for understanding the relationship between chemical bonding and those molecular properties that help to determine medicinal activity. This book explores the basic aspects of structural organic chemistry without going into the various classes of reactions. Two medicinal chemistry concepts are also introduced: partition coefficients and the nomenclature of cyclic and polycyclic ring systems that comprise a large number of drug molecules. Given the systematic name of a drug, the reader is guided through the process of drawing an accurate chemical structure. By emphasizing the relationship between structure and properties, this book gives readers the connections to more fully comprehend, retain, apply, and build upon their organic chemistry background in further chemistry study, practice, and exams.

    Homolytic Aromatic Substitution deals with the theoretical aspects of homolytic aromatic substitution reactions. The effect of various kinds of free radicals on the substitution of atoms or groups (usually hydrogen) attached to aromatic nuclei is examined, and the preparative use of homolytic substitution reactions is also considered. This book is comprised of seven chapters and begins with an introduction to the general characteristics of homolysis, along with homolytic and heterolytic aromatic substitution. The discussion then turns to the various theoretical approaches used to rationalize aromatic substitution, particularly those that are germane to a consideration of the problems of orientation and reactivity in homolytic substitution. The following chapters explore homolytic arylation reactions, including those between aryl radicals and aromatic substrates; relative rates of arylation and partial rate factors for phenylation; the reaction mechanism underlying intramolecular arylation; and homolytic alkylation reactions. The final chapter deals with hydroxylation and some other substitution reactions such as benzoyloxylation, acetyloxylation, halogenation, amination and amidation, and mercuration. This monograph will be of interest to organic chemists.

  • Hydrothermal and Supercritical Water Processes

    • Inglés
    Hydrothermal and Supercritical Water Processes presents an overview on the properties and applications of water at elevated temperatures and pressures. It combines fundamentals with production process aspects. Water is an extraordinary substance. At elevated temperatures (and pressures) its properties change dramatically due to the modifications of the molecular structure of bulk water that varies from a stable three-dimensional network, formed by hydrogen bonds at low and moderate temperatures, to an assembly of separated polar water molecules at high and supercritical temperatures. With varying pressure and temperature, water is turned from a solvent for ionic species to a solvent for polar and non-polar substances. This variability and an enhanced reactivity of water have led to many practical applications and to even more research activities, related to such areas as energy transfer, extraction of functional molecules, unique chemical reactions, biomass conversion and fuel materials processing, destruction of dangerous compounds and recycling of useful ones, growth of monolithic crystals, and preparation of metallic nanoparticles. This book provides an introduction into the wide range of activities that are possible in aqueous mixtures. It is organized to facilitate understanding of the main features, outlines the main applications, and gives access to further information
