In 1949 Simons and his coworkers published a long paper in the Journal of the Electrochemical Society. [3] The Simons process is used for the production of perfluorinated amines, ethers, carboxylic acids, and sulfonic acids. For carboxylic and sulfonic acids, the products are the corresponding acyl fluorides and sulfonyl fluorides. The method ...
Introducing the carbon–fluorine bond to organic compounds is the major challenge for medicinal chemists using organofluorine chemistry, as the carbon–fluorine bond increases the probability of having a successful drug by about a factor of ten. [30] Over half of agricultural chemicals contain C-F bonds. A common example is trifluralin. [31]
Tetrafluoroethylene is a reactive molecule that participates in myriad reactions. Owing to the presence of four fluorine substituents, its reactions differ strongly from the behavior of conventional alkenes such as ethylene. Tetrafluoroethylene dimerizes, giving octafluorocyclobutane. Even normal alkenes and dienes add tetrafluoroethylene in a ...
George A. Olah, Nobel Prize in Chemistry winner in 1994, gave a plenary lecture at the 15th ISFC (Vancouver, 1997). [5] The Book of Abstracts of 13th ISFC has been published as a special issue of the Journal of Fluorine Chemistry. [6] The Book of Abstract of 21st ISFC can be tracked by its ISBN. [7]
Fluorine's chemistry is dominated by its strong tendency to gain an electron. It is the most electronegative element and elemental fluorine is a strong oxidant. The removal of an electron from a fluorine atom requires so much energy that no known reagents are known to oxidize fluorine to any positive oxidation state. [20]
She has spent much of her career advocating for women chemists and research into fluorine chemistry, serving on a variety of committees for the American Chemical Society and American Association for the Advancement of Science. She has also been recognized for her teaching and mentorship to approximately 130 post-doctoral researchers.
Fluorine gas (F 2) can act both as an electrophilic and atomic source of fluorine. [4] The weak F–F bond strength (36 kcal/mol (150 kJ/mol) [5]) allows for homolytic cleavage. The reaction of F 2 with organic compounds is, however, highly exothermic and can lead to non-selective fluorinations and C–C cleavage, as well as explosions. [6]
