  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. Historically, only three atomic fluorine sources were available for radical ...

  3. Fluorine - Wikipedia

    en.wikipedia.org/wiki/Fluorine

    Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen [note 1] and exists at standard conditions as pale yellow diatomic gas. Fluorine is extremely reactive as it reacts with all other elements except for the light inert gases. It is highly toxic.

  4. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    finkelstein-reaction. RSC ontology ID. RXNO:0000155. The Finkelstein reaction, named after the German chemist Hans Finkelstein, [1] is a type of S N 2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an equilibrium reaction, but the reaction can be driven to completion ...

  5. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Halogenation. In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide -containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1] This kind of conversion is in fact so common that a comprehensive overview is ...

  6. SN2 reaction - Wikipedia

    en.wikipedia.org/wiki/SN2_reaction

    In the S N 2 reaction, a strong nucleophile forms a new bond to an sp 3 -hybridised carbon atom via a backside attack, all while the leaving group detaches from the reaction center in a concerted (i.e. simultaneous) fashion. The name S N 2 refers to the Hughes-Ingold symbol of the mechanism: "S N " indicates that the reaction is a nucleophilic ...

  7. Dehalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehalogenation

    Dehalogenation. In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon - halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine), dechlorination (removal of chlorine), debromination (removal of ...

  8. Electrophilic halogenation - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_halogenation

    Electrophilic halogenation. In organic chemistry, an electrophilic aromatic halogenation is a type of electrophilic aromatic substitution. This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. A few types of aromatic compounds, such as phenol, will react without a catalyst ...

  9. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    The carbon–fluorine bond of the smaller molecules is formed in three principal ways: Fluorine replaces a halogen or hydrogen, or adds across a multiple bond. The direct reaction of hydrocarbons with fluorine gas can be dangerously reactive, so the temperature may need to be lowered even to −150 °C (−240 °F). [115] "
