  2. Radical fluorination - Wikipedia

    en.wikipedia.org/wiki/Radical_fluorination

    Radical fluorination is a type of fluorination reaction, complementary to nucleophilic and electrophilic approaches. [1] It involves the reaction of an independently generated carbon-centered radical with an atomic fluorine source and yields an organofluorine compound .

  3. Organofluorine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organofluorine_chemistry

    Organofluorine compounds are prepared by numerous routes, depending on the degree and regiochemistry of fluorination sought and the nature of the precursors. The direct fluorination of hydrocarbons with F 2, often diluted with N 2, is useful for highly fluorinated compounds: R 3 CH + F 2 → R 3 CF + HF

  4. Hydrodefluorination - Wikipedia

    en.wikipedia.org/wiki/Hydrodefluorination

    In reductive hydrodefluorination the fluorocarbon is reduced in a series of single electron transfer steps through the radical anion, the radical and the anion with ultimate loss of a fluorine anion. An example is the conversion of pentafluorobenzoic acid to 3,4,5-tetrafluorobenzoic acid in a reaction of zinc dust in aqueous ammonia.

    After officially graduating from Kyuranger in the summer movie Uchu Sentai Kyuranger vs Space Squad, he held a birthday live in Shibuya and announced his major debut in December. Kishi's first mini-album, titled Hashitai wake janai (走りたいわけじゃない) is released by Nippon Columbia on 5 December.

  6. Electrochemical fluorination - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_fluorination

    Electrochemical fluorination (ECF), or electrofluorination, is a foundational organofluorine chemistry method for the preparation of fluorocarbon-based organofluorine compounds. [1] The general approach represents an application of electrosynthesis .

  7. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction. With chlorine the reaction is moderate to fast; with bromine, slow and requires intense UV irradiation ; and with iodine, it is practically nonexistent and thermodynamically unfavored.

  8. Selectfluor - Wikipedia

    en.wikipedia.org/wiki/Selectfluor

    Electrophilic fluorinating reagents could in principle operate by electron transfer pathways or an S N 2 attack at fluorine. This distinction has not been decided. [2] By using a charge-spin separated probe, [3] it was possible to show that the electrophilic fluorination of stilbenes with Selectfluor proceeds through an SET/fluorine atom transfer mechanism.
