Organofluorine Chemistry

• Gebundenes Buch

Produktbeschreibung

The replacement of hydrogen with fluorine in organic molecules can profoundly influence their chemical and physical properties, leading to a range of compounds with highly desirable properties. These molecules are of interest across the wide spectrum of industrial and academic organic chemistry, so that organofluorine chemistry is economically highly important. Organofluorine Chemistry will help chemists to develop a systematic knowledge of the chemistry of fluorine with a view towards its application in the design of new reactions and syntheses, and the creation of novel fluorinated molecules and materials. With initial chapters focusing on why fluorine creates such unique properties in organic compounds, the book then covers general reactions of fluorine. Coverage is chosen from the recent research literature, concentrating on the development of novel bioactive compounds and catalytic ligands, and explaining, in the context of the initial chapters, how and why fluorine is so effective. With a final chapter covering the general synthetic chemistry of organofluorine compounds, the book is a cohesive summary of the fundamental principals of organofluorine chemistry.
