Questions And Answer

• Bromoquinoline

  There are seven positional isomers of bromoquinoline and their main properties are listed below:
  ;

• Application and synthetic method

  3-bromo-quinoline is reacted with mixed acid for generating 3-bromo-5-nitro-quinoline, which heats together with potassium permanganate for being oxidation into 5-bromo-2, 3-pyridine dicarboxylic acid.
  6-bromo-quinoline is heated together with nitric acid to generate 6-bromo-8-nitro quinolone with further reaction with potassium permanganate for being oxidized to 2, 3-pyridinedicarboxylic acid.
  2-bromo-quinolien can be synthesized through the reaction between 2-hydroxy quinoline and phosphorus pentabromide.
  Quinoline perbromide is heated at 180 °C for generating 3-bromo-quinoline.
  From the heating between 4-hydroxy quinoline and phosphorus pentabromide, or from the diazotization reaction via 4-aminoquinoline to generate 4-bromo-quinoline;
  5-bromo-quinoline is synthesize by the heating reaction between m-bromo-aniline, glycerol, m-bromo nitrobenzene and concentrated sulfuric acid, or from the diazotization reaction of 5-aminoquinoline.
  6-bromo-quinoline can be synthesized from the heating of bromoaniline, glycerol, concentrated sulfuric acid, and p-bromo-nitrobenzene. 7-bromo-quinoline can be synthesized from the diazotization reaction of 7-aminoquinoline.
  8-bromo-quinoline can be synthesized from the heating reaction of o-bromo-aniline, glycerol, concentrated sulfuric acid and o-bromo nitrobenzene.
  application: as organic synthesis reagents.
