Book Description
Organic Sulfur Compounds, Volume I deals with the chemistry of organic sulfur compounds such as disulfides, polysulfides, olefins, acetylenes, and chloroethylenes. Topics covered range from the inorganic acids of sulfur and the thermodynamics of organic sulfur compounds to some applications of isotopic sulfur and the stereochemistry of disulfides and polysulfides. The mechanism of oxidation of thiols to disulfides is also discussed. Comprised of 40 chapters, this volume first considers the precise structures of elemental sulfur in relation to the reactions of sulfur compounds, followed by an analysis of the inorganic acids of sulfur. The reader is then introduced to the thermodynamics of organic sulfur compounds and the bonding characteristics of the sulfur atom, as well as the infrared spectra of organosulfur compounds. Subsequent chapters focus on the ionic scission of the sulfur-sulfur bond; nucleophilic reactions of thiols with acetylene and chloroethylene; reactions of sulfur with olefins; and the chemistry of isothiocyanates. This book should prove useful to advanced students, practitioners, and research workers in the field of organic chemistry.

Book Description
In recent years organic sulfur chemistry has been growing at an even faster pace than the very rapid development in other fields of chemistry. This phenomenal growth is undoubtedly a reflection of industrial and public demands: not only was sulfur recently in overall surplus for the first time in the history of the chemical industry but it has now become a prin cipal environmental hazard in the form of sulfur dioxide, sulfuric acid and hydrogen sulfide. Another reason, discernible in the last fifteen years, has been the desire, on the part of individual chemists and all types of research managers, to move away from the established chemistry of carbon into the less well understood and sometimes virgin chemistries of the other elements which form covalent bonds. As a result of this movement the last decade has seen the development of sulfur chemistry into a well-organized and now much better understood branch of organic chemistry. Enough of the detail has become clear to see mechanistic interrelationships between previously unconnected reactions and with this clarification the whole subject has in tum become systema tized and subdivided. The divalent sulfur chemistry of thiols, monosulfides, disulfides and polysulfides is a large area in itself, much of it devoted to oxidation-reduction and the breakage and formation of sulfur-sulfur bonds, although interesting discoveries are now being made about the reac tivity of certain sulfur-carbon bonds. Of course, this area has its own mas sive biochemical branch involving enzymes and proteins.

Book Description
"This book is for you, and every text feature is meant to help you learn and succeed in your chemistry course. I wrote this book with two main goals for you in mind: to see chemistry as you never have before and to develop the problem-solving skills you need to succeed in chemistry. I want you to experience chemistry in a new way. I have written each chapter to show you that chemistry is not just something that happens in a laboratory; chemistry surrounds you at every moment. Several outstanding artists have helped me to develop photographs and art that will help you visualize the molecular world. From the opening example to the closing chapter, you will see chemistry. My hope is that when you finish this course, you will think differently about your world because you understand the molecular interactions that underlie everything around you. My second goal is for you to develop problem-solving skills. No one succeeds in chemistry-or in life, really-without the ability to solve problems. I can't give you a one-size-fits-all formula for problem solving, but I can and do give you strategies that will help you develop the chemical intuition you need to understand chemical reasoning"--

Book Description
The volume describes about 1250 acyclic sulfur-nitrogen compounds with three- and four-coordinate sulfur in the formal oxidation state IV. Major classes of compounds comprise the species X2S=NR (X=halogen, OR', NR'2, etc.; R=H, halogen, organyl; R'=organyl), (R2N)3S+ (R=alkyl), R2NS(O)X (X=halogen, OH, OR, SR, NR2, R=organyl), (OSNH)x, F2S(NR2)2, and F3SNR2. N, N-Diethylamidotrifluorosulfur, also known under the acronym DAST, has become a very popular fluorinating agent in recent years. Correspondingly, the use of DAST in inorganic and organic chemistry is exemplified with numerous reactions. Some examples are the metathetical exchange reactions converting reactive chlorides into fluorides: SOCl2 -> SOF2, PCl3 -> PF3, (CH3)3SiCl -> (CH3)3SiF, and RC(O)Cl -> RC(O)F. Others include the conversion of (C6H5)3P into (C6H5)3PF2 and of (R3NC(S)S)2 into R2NCF3, R=alkyl. In organic chemistry, fluorides are easily accessible from alcohols, geminal fluorides RR'CF2 from the respective aldehydes or ketones, and acyl fluorides RC(O)F from carboxylic acides by using DAST. Because DAST is easy to handle and gives clean reactions in syntheses, this Gmelin volume devotes much space to the description of the chemical and physical properties od DAST.

Book Description
'Natural Compounds: Plant Sources, Structure and Properties' details the properties of over 7,500 chemical compounds of pharmacological interest found in plants. Each volume systematically covers occurrence of the compounds in plants, illustrations of chemical structures plus physical-chemical, spectral, and pharmacological data. Entries are indexed by plant name, subject, and pharmacological property. This provides unique coverage of information on compounds isolated from some 3,000 plants, including many from central Asia and Russia, that are not well known elsewhere. The entries for each compound share a similar format. The entries are preceded by tabulated information on the occurrence of the compounds in plants etc. The highly experienced team of compilers from the renowned Institute of the Chemistry of Plant Substances in Tashkent have expertly assessed the international literature and include data only when confident of its validity, e.g. excluding data where measurement processes cause degradation of the original compound.

Book Description
The present volume is the first of a series describing acyclic sulfur-nitrogen compounds with sulfur of oxidation number IV. The acyclic sw-N compounds are arranged according to the coordination number of the sulfur. Neutral compounds are described before ions and complex compounds. The preceding series "Sulfur-Nitrogen Compounds" Parts 2, 3, and 4 covers the cyclic sw-N compounds. In this volume, the first section deals with sulfur-nitrogen compounds with 1-coordinate sulfur and begins with the sulfur nitride {thiazyl) radical, SN. This transient molecule was observed in its electronic ground state and several electronically excited states. The descrip tions of the sulfur nitride (thiazyl) ions SN+ and SW follow. The SN+ ionwas studied in the gas phase as weil as in the solid state where it forms salts. Thionitrosyl complexes containing the SN Iigand as a terminal linear unit are described at the end of the first section. The second section concerns Sulfur-nitrogen compounds with 2-coordinate sulfur and starts with the description of poly(sulfur nitride), (SNlx· The preparation, crystal structure, and metallic and superconducting properties of (SN)x, which were extensively studied, fill a !arge part of the volume. Halogen-modified poly(sulfur nitride) such as the widely studied (SNBr )x 04 and Na-modified poly(sulfur nitride) are dealt with in the following chapters.
