    en.wikipedia.org/wiki/Borsche–Drechsel_cyclization

    Borsche–Drechsel cyclization is the central step in Borsche–Drechsel carbazole synthesis, where in the first step phenylhydrazine is condensed with cyclohexanone to form the cyclohexanone phenylhydrazone, and in the final step the resulting tetrahydrocarbazole is oxidized to carbazole itself.

  3. Carbazole - Wikipedia

    en.wikipedia.org/wiki/Carbazole

    Bucherer carbazole synthesis. A third method for the synthesis of carbazole is the Graebe–Ullmann reaction. Graebe–Ullmann reaction. In the first step, an N-phenyl-1,2-diaminobenzene (N-phenyl-o-phenylenediamine) is converted into a diazonium salt which instantaneously forms a 1,2,3-triazole. The triazole is unstable and at elevated ...

    en.wikipedia.org/wiki/Dakin_oxidation

    The Dakin oxidation. The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate.

  7. Bucherer carbazole synthesis - Wikipedia

    en.wikipedia.org/wiki/Bucherer_carbazole_synthesis

    The Bucherer carbazole synthesis is a chemical reaction used to synthesize carbazoles from naphthols and aryl hydrazines using sodium bisulfite.

  8. Polychlorinated carbazoles - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_carbazoles

    They are derivatives of carbazole and nitrogen analogues of polychlorinated dibenzofurans. Polychlorinated carbazoles usually occur as a mixture of various isomers. This mixture can have a certain frequency pattern (congener pattern) from which conclusions can be drawn about the causes of formation. PCCZs are not manufactured purposefully.
