  2. Hexachlorocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Hexachlorocyclohexane

    Chlorination of benzene under electrophilic aromatic substitution conditions (Cl 2 /FeCl 3 or Cl 2 /AlCl 3) produces chlorobenzene.Since mono chloro-de-hydrogenation deactivates the molecule against further electrophilic reactions, the reaction can be halted at one chlorine atom substitution.

  3. Aluminium chloride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_chloride

    Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3.It forms a hexahydrate with the formula [Al(H 2 O) 6]Cl 3, containing six water molecules of hydration.

  4. tert-Butylbenzene - Wikipedia

    en.wikipedia.org/wiki/Tert-Butylbenzene

    tert-Butylbenzene can be produced by the treatment of benzene with isobutene [1] or by the reaction of benzene with tert-butyl chloride in presence of anhydrous aluminium chloride, [2] the latter is depicted below:

  5. Electrophilic halogenation - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_halogenation

    A few types of aromatic compounds, such as phenol, will react without a catalyst, but for typical benzene derivatives with less reactive substrates, a Lewis acid is required as a catalyst. Typical Lewis acid catalysts include AlCl 3, FeCl 3, FeBr 3 and ZnCl 2. These work by forming a highly electrophilic complex which is attacked by the benzene ...

  6. Disulfur dichloride - Wikipedia

    en.wikipedia.org/wiki/Disulfur_dichloride

    In the presence of aluminium chloride (AlCl 3), S 2 Cl 2 reacts with benzene to give diphenyl sulfide: 8 S 2 Cl 2 + 16 C 6 H 6 → 8 (C 6 H 5 ) 2 S + 16 HCl + S 8 Anilines (1) react with S 2 Cl 2 in the presence of NaOH to give 1,2,3-benzodithiazolium chloride (2) ( Herz reaction ) which can be transformed into ortho -aminothiophenolates (3 ...

  7. Electrophilic aromatic substitution - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_aromatic...

    The most widely practised example of this reaction is the ethylation of benzene. Approximately 24,700,000 tons were produced in 1999. [2] (After dehydrogenation and polymerization, the commodity plastic polystyrene is produced.) In this process, acids are used as catalyst to generate the incipient carbocation. Many other electrophilic reactions ...

  8. Hexachlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Hexachlorobenzene

    In 1867, Henry Bassett proved that the compound produced from benzene and antimony was the same as Julian's carbon chloride and named it "hexachlorobenzene". [ 10 ] [ 9 ] Leopold Gmelin named it "dichloride of carbon" and claimed that the carbon was derived from cast iron and the chlorine was from crude saltpetre .

  9. Chlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Chlorobenzene

    Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.
