The compilation further considers pentahalides of transition metals and halide chemistry of chromium, molybdenum, and tungsten. The book closes with discussions on halogen chemistry of actinides and halogeno metal carbonyls and related compounds. Covered areas include trivalent, tetravalent, pentavalent, and hexavalent actinides, and structures and reactions of halogeno metal carbonyls. The compilation is a valuable source of information for readers interested in the study of halogens.

Für das Verständnis der organischen Chemie muss man wissen, worum es sich bei funktionalen Gruppen handelt. Dieses Fachbuch steht ganz in der Tradition der Reihe Patai's Chemistry of Functional Groups. Jeder Band deckt sämtliche Aspekte funktionaler Gruppen ab und behandelt dabei theoretische, analytische, synthetische, biologische Aspekte sowie Belange der Industrie. Hypervalente Halogenverbindungen, insbesondere Jodverbindungen, sind überaus effiziente und selektive Oxidantien für eine Vielzahl funktionaler Gruppen. Die elektrophilen Eigenschaften dieser Reagenzien können auch für die Einführung anderer Funktionalisierungen verwendet werden. Dieser Band ist der erste in der Reihe, die die Eigenschaften und das chemische Verhalten von hypervalentem Jod und Brom, deren Einsatz in der organischen Synthese sowie deren industrielle Anwendung untersucht. Wie bei allen neuen Bänden, werden die Kapitel zunächst online in Patai's Chemistry of Functional Groups veröffentlicht. Wenn ein Band online vervollständigt ist, erfolgt die Herausgabe als Printversion. Die Printfassung entspricht der Qualität, die man von der Patai-Reihe kennt, und bietet auch einen umfassenden Index.

Analytical Chemistry of Organic Halogen Compounds presents the procedures applied in the analysis of organic halogen compounds. This book is composed of eight chapters that discuss the methods involved in the production and application of organic halogen compounds and in overcoming contamination problems caused by these compounds. After briefly dealing with the preparation, characteristics, and reactions of organic halogen compounds, this book goes on discussing the fundamental concepts of methods for the detection of halogens in organic compounds, namely, chlorine, bromine, iodine, and fluorine. The following chapter describes the characteristic features, advantages, and disadvantages of ultramicro and submicro chemical methods. A chapter also examines the qualitative and quantitative studies of organic halogen compounds based on the thermal and chemical stability of these compounds. The concluding chapters discuss the interference or interfering effects of halogens and their elimination in the determination of other elements. A list of physical constants of organic halogen compounds of general pharmaceutical and industrial significance is provided. This book is an ideal source for analytical chemists and other workers who are interested in the theoretical bases of the methods.

Long-awaited on the importance of halogen bonding in solution, demonstrating the specific advantages in various fields - from synthesis and catalysis to biochemistry and electrochemistry! Halogen bonding (XB) describes the interaction between an electron donor and the electrophilic region of a halogen atom. Its applicability for molecular recognition processes long remained unappreciated and has mostly been studied in solid state until recently. As most physiological processes and chemical reactions take place in solution, investigations in solutions are of highest relevance for its use in organic synthesis and catalysis, pharmaceutical chemistry and drug design, electrochemistry, as well as material synthesis. Halogen Bonding in Solution gives a concise overview of halogen bond interactions in solution. It discusses the history and electronic origin of halogen bonding and summarizes all relevant examples of its application in organocatalysis. It describes the use of molecular iodine in catalysis and industrial applications, as well as recent developments in anion transport and binding. Hot topic: Halogen bonding is an important interaction between molecules or within a molecule. The field has developed considerably in recent years, with numerous different approaches and applications having been published. Unique: There are several books on halogen bonding in solid state available, but this will be the first one focused on halogen bonding in solution. Multi-disciplinary: Summarizes the history and nature of halogen bonding in solution as well as applications in catalysis, anion recognition, biochemistry, and electrochemistry. Aimed at facilitating exciting future developments in the field, Halogen Bonding in Solution is a valuable source of information for researchers and professionals working in the field of supramolecular chemistry, catalysis, biochemistry, drug design, and electrochemistry.

In spite of their adjacency in the periodic table, halogens and nonmetals have very different properties. Halogens are among the most chemically reactive elements in the periodic table, exhibiting a diverse chemistry in terms of the large numbers of compounds they can form. On the other hand, noble gases are the least chemically reactive elements. In fact, before the 1960s, chemists referred to these elements as inert gases, because it was believed that they exhibited no chemistry whatsoever. Providing the basics of these elements, including their role in history and some of the important scientists involved in their discovery, this newly updated, full-color resource features up-to-date scientific understanding in a clear and accessible format. Halogens and Noble Gases, Second Edition examines the ways humans use halogens and noble gases and the resulting benefits and challenges to society, health, and the environment. Fluorine, chlorine, bromine, iodine, helium, and krypton are covered in this eBook, along with the fundamentals of chemistry and physics as well as possible future developments in halogen and noble gas science and its applications.

The Chemistry of Chlorine, Bromine, Iodine and Astatine is a special edition that contains selected sections and addresses the needs of specialists in their respective fields. The text describes the general atomic properties of non-metals, particularly the halogens, as being the perfect series to study, both in physical and chemical terms. The book explains that the combination of the atomic properties implies excellent electronegativity values for the halogen atoms. The text also cites some behavior characteristics of halogens that are irregular, such as chlorine and bromine are similar but differ from fluorine on one side and iodine on the other. The book also compares the general methods of producing chlorine, bromine, or iodine by 1) oxidation of halide derivatives or 2) reduction of compounds of the halogens in positive oxidation states. The text then reviews the application of a complex valence theory that raises difficult questions about the bonding in halogen-oxygen molecules. The book also explains the biological behavior of astatine that accumulates in the liver or in the thyroid gland depending on the method of administration either as a radiocolloid or as a true solution. The book is suitable for molecular biologists and researchers, molecular chemists, and medical researchers.

With contributions by numerous experts

The book summarizes the knowledge and experiences concerning the role of halogens during various geochemical processes, such as diagenesis, ore-formation, magma evolution, metasomatism, mineralization, and metamorphism in the crust and mantle of the Earth. It comprises the role of halogens in other terrestrial worlds like volatile-rich asteroids, Mars, and the ice moons of Jupiter and Saturn. Review chapters outline and expand upon the basis of our current understanding regarding how halogens contribute to the geochemical/geophysical evolution and stability of terrestrial worlds overall.

It is a matter of pleasure for me to present this English edition of the book of Organic Chemistry for the studens of B.Sc. Part-I.
