    en.wikipedia.org/wiki/4-methylcatechol

    Calone, a derivative of 4-methylcatechol, is known in the fragrance industry as "watermelon ketone" for its distinctive odor. [3]The brand of low-temperature coke used as a smokeless fuel Coalite obtains homocatechol from ammoniacal liquor by solvent extraction, distillation and crystallisation.

  6. Piperonal - Wikipedia

    en.wikipedia.org/wiki/Piperonal

    Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.

  9. Dakin oxidation - Wikipedia

    en.wikipedia.org/wiki/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. Overall, the carbonyl group is oxidised, whereas the H 2 O 2 is reduced.
