The report covers the synthesis of fluorine-containing benezenediazooxides. Compounds of particular interest are tetrafluoro-ortho- and para-benezenediazooxides. Tetrafluoro-ortho- and para-benezenediazooxides were synthesized and characterized by infrared and nuclear magnetic resonance. Triphenylphosphine, beta-naphthol, and N, N-dimethylaniline were found to couple with the tetrafluoro-para-benezenediazooxide; however, attempts to form derivatives of the tetrafluoro-ortho-benezenediazooxide were unsuccessful. Methoxytri-fluoro-1, 4-benezenediazooxide was synthesized from 2, 3, 5, 6-tetrafluoro-para-anisidine. The structure of this diazooxide and the mechanism of reaction are under investigation. (Author).
The definitive guide to creating fluorine-based compounds—and the materials of tomorrow Discovered as an element by the French chemist Henri Moissan in 1886, through electrolysis of potassium fluoride in anhydrous hydrogen fluoride—"le fluor," or fluorine, began its chemical history as a substance both elusive and dangerous. With a slight pale yellow hue, fluorine is at room temperature a poisonous diatomic gas. Resembling a spirit from a chemical netherworld, fluorine is highly reactive, difficult to handle, yet very versatile as a reagent—with the power to form compounds with almost any other element. Comprising 20% of pharmaceutical products and 30% of agrochemical compounds, as well as playing a key role in electric cars, electronic devices, and space technology, compounds containing fluorine have grown in importance across the globe. Learning how to safely handle fluorine in the preparation of innovative new materials—with valuable new properties—is of critical importance to chemists today. Bringing together the research and methods of leading scientists in the fluorine field, Efficient Preparations of Fluorine Compounds is the definitive manual to creating, and understanding the reaction mechanisms integral to a wide variety of fluorine compounds. With sixty-eight contributed chapters, the book's extensive coverage includes: Preparation of Elemental Fluorine Synthesis Methods for Exotic Inorganic Fluorides with Varied Applications Introduction of Fluorine into Compounds via Electrophilic and Nucleophilic Reactions Direct Fluorination of Organic Compounds with Elemental Fluorine Efficient Preparations of Bioorganic Fluorine Compounds Asymmetric Fluorocyclization Reactions Preparations of Rare Earth Fluorosulfides and Oxyfluorosulfides The book offers methods and results that can be reproduced by students involved in advanced studies, as well as practicing chemists, pharmaceutical scientists, biologists, and environmental researchers. The only chemical resource of its kind, Efficient Preparations of Fluorine Compounds—from its first experiment to its last—is a unique window into the centuries old science of fluorine and the limitless universe of fluorine-based compounds.
Written by a leading expert in the field, this is a comprehensivereview of the methods for preparing stereochemically definedfluorine-containing compounds of biomedical importance. Fluorinated organic compounds are well known for their unusualreactivity but the growing importance of these compounds in thebiomedical field has been accompanied by an increasing awareness ofthe necessity to synthesise and explore the biological propertiesof stereochemically defined fluoro-compounds. This is the firstbook written on this exciting area of research. It contains: * detailed reviews on stereocontrolled synthesis of biologicallyimportant compounds * 21 chapters covering the main areas of asymmetric synthesis andbiocatalysts where fluorine plays a key role * mechanisms and methods for synthesizing fluoro-organiccompounds Written for professionals involved in organic, physical andorganofluorine chemistry, natural product synthesis, biological,pharmaceutical and other life science related industries.
This republication of an established classic coincides with a surge in the indistrial development of fluorine chemistry. Comprehensive and authoritative, it provides finger tip access to methods for introducing small or large numbers of fluorine atoms into organic chemistry. Serving as a practical bench manual and source book for theoretical and industrial knowledge, the reference provides 3,857 references to the original literature; 1,520 illustrated equations indicating reactions and yields of fluorinated products; more than 200 detailed experimental procedures indicating types of reagent that can be used, types of compounds with which they react, and types of products that can be prepared; over 200 tables of highly relevant data; and much more.
