Interpretation of the Ultraviolet Spectra of Natural Products focuses on the ultraviolet spectrum of chromophores. The book first discusses single chromophores, including absorption due to electron lone pairs in saturated systems and absorption of olefins, alkynes, carbonyl compounds, and thiocarbonyl compounds. The text also takes a look at conjugated chromosomes, such as polyenes, enynes, and conjugated azomethines. The selection also evaluates C-aromatic compounds. Topics include benzenoid and hydrocarbons; phenols and their ethers; styrenes and stilbenes; aromatic carbonyl compounds; and nitro compounds. The text also discusses O- and S- heteroaromatic compounds and N-heteroaromatic compounds. The book highlights the applications of spectrophotometry to the analysis of natural products. Topics include formation of derivatives having absorbing chromophores; reactions leading to changes in absorption of added reagents; and analyses involving transformation to products suitable for spectrophotometry. The text is a good reference for readers wanting to explore chromophores.

Applications of Nuclear Magnetic Resonance Spectroscopy in Organic Chemistry, Second Edition focuses on the applications of nuclear magnetic resonance spectroscopy to problems in organic chemistry and the theories involved in this kind of spectroscopy. The book first discusses the theory of nuclear magnetic resonance, including dynamic and magnetic properties of atomic nuclei, nuclear resonance, and relaxation process. The manuscript also examines the experimental method. Topics include experimental factors that influence resolution and the shapes of absorption lines; measurement of line positions and identification of the chemical shift; and measurement of intensities. The text reviews the theories of chemical effects in nuclear magnetic resonance spectroscopy and spin-spin multiplicity and the theory and applications of multiple irradiation. The book also tackles the theory of chemical shift, including the classification of shielding effects, local diamagnetic proton shielding, solvent effects, and contact shifts. The publication is a dependable source of data for readers interested in the applications of nuclear magnetic resonance spectroscopy.

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.

Synthetic Analgesics, Part I: Diphenylpropylamines deals with the methods of synthesis, the physical and chemical properties, and the ""analgesic"" activity of diphenylpropylamines. Topics covered include the ""analgesic"" activity of methadone, morphine, pethidine, and codeine in animals; diamines and derivatives; R875 and related basic tertiary amides; esters derived from amino acids and secondary and tertiary alcohols; and ketimines, acyl ketimines, and ketones. This book is comprised of 21 chapters and begins with a brief background on the first chemical and pharmacological experiments on diphenylpropylamines, followed by a discussion on ""analgesic"" activity in humans and animals. The ""analgesic"" activity of methadone, morphine, pethidine, and codeine in animals is considered. The following chapters explore a variety of compounds such as 3:3-diphenylpropylamines, tertiary alcohols, secondary alcohols, primary alcohols, nitriles, diamines and derivatives, primary and secondary amides, acids and acid chlorides, and aldehydes. Sulfones, dissociation constants, and configurational studies are also described. This monograph will be a useful resource for researchers and practitioners in the fields of organic chemistry, analytical chemistry, and pharmacology.

Organophosphorus Monomers and Polymers is the first attempt at a generalization and systemization of existent knowledge of the methods of synthesis and the basic properties of monomers and polymers of organophosphorus compounds, and also of their fields of application. It contains valuable reference material, collated in tables (physical constants of the monomers, properties of the polymers and copolymers, etc.). The literature used by the author has covered journals, patents and books up to 1958, and in some cases more recent results are included. The monomers and polymers are tabulated according to the particular class of phosphorus-containing compounds to which they belong: acids of phosphorus, their derivatives, phosphines, polymers and co-polymers of unsaturated esters of acids of phosphorus, etc. Groups of monofunctional unsaturated phosphorus-containing compounds (acids, acid chlorides, amides, etc.) are listed in the order of: (a) the distance of the multiple bonds from the phosphorus atom, and (b) the number of multiple bonds. Within each group, the unsaturated substances are listed from simple to complex according to the rules laid down in The Chemist''s Handbook. The book is intended for scientists, research workers, engineers, and technologists working on the preparation, manipulation, and investigation of monomers and high molecular weight compounds, and also for students studying related branches of chemistry.

Boron Fluoride and Its Compounds as Catalysts in Organic Chemistry deals with the concerns associated with the utilization of boron fluoride as a catalyst. The title provides a comprehensive account of boron fluoride, such as its properties, compounds, and related methodologies. The coverage of the text includes the preparation and recovery of boron fluoride, along with the physical and chemical properties. The selection also covers various boron fluoride compounds and their respective reaction to various processes, such as alkylation, polymerization, and nitration. The book will be of great interest to students, researchers, and practitioners of organic chemistry.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfängen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen für die historische wie auch die disziplingeschichtliche Forschung zur Verfügung, die jeweils im historischen Kontext betrachtet werden müssen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.
