  2. Organochlorine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organochlorine_chemistry

    H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides.

  3. 4-Fluoroaniline - Wikipedia

    en.wikipedia.org/wiki/4-Fluoroaniline

    4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene. [2] It is a common building block in medicinal chemistry and related fields. [3] For example, it is a precursor to the fungicide fluoroimide or the fentanyl analogue parafluorofentanyl. It has also been evaluated for the production of ligands for homogeneous catalysis ...

  4. 4-Chloroaniline - Wikipedia

    en.wikipedia.org/wiki/4-Chloroaniline

    4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin , anilofos , monolinuron , and chlorphthalim .

  5. 4-Fluoronitrobenzene - Wikipedia

    en.wikipedia.org/wiki/4-Fluoronitrobenzene

    4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline, [3] which is a precursor to the fungicide fluoroimide and parafluorofentanyl. Owing to the presence of the electron withdrawing nitro group, the fluoride is a good leaving group in fluoronitrobenzenes. Thus reaction with phenoxide gives the mononitrodiphenylether. [4]

    Other products such as CH 2 Cl 2 may also form. Chain termination Two free radicals (chlorine and chlorine, chlorine and methyl, or methyl and methyl) combine: Methane chlorination: termination The last possibility generates in an impurity in the final mixture (notably, an organic molecule with a longer carbon chain than the reactants).

  9. Chlorofluorocarbon - Wikipedia

    en.wikipedia.org/wiki/Chlorofluorocarbon

    An easy example is that of CFC-12, which gives: 90+12=102 -> 1 carbon, 0 hydrogens, 2 fluorine atoms, and hence 2 chlorine atoms resulting in CCl 2 F 2. The main advantage of this method of deducing the molecular composition in comparison with the method described in the paragraph above is that it gives the number of carbon atoms of the molecule.
