| Use and preparation method | 3-bromoquinoline reacts with mixed acid to generate 3-bromo-5-nitroquinoline, which is oxidized to 5-bromo-2, 3-pyridinedicarboxylic acid when heated with potassium permanganate. 6-bromoquinoline and nitric acid are heated to form 6-bromo-8-nitroquinoline, which is oxidized to 2, 3-pyridinedicarboxylic acid when interacting with potassium permanganate. 2-bromoquinoline is prepared by the reaction of 2-hydroxyquinoline and phosphorus pentabromide. 3-bromoquinoline was prepared by heating quinoline perbromide at 180 ℃. 4-bromoquinoline is prepared by heating 4-hydroxyquinoline with phosphorus pentabromide, or by diazotization reaction of 4-aminoquinoline. 5-bromoquinoline is prepared by heating m-bromoaniline, glycerol, m-bromonitrobenzene and concentrated sulfuric acid, or by diazotization reaction of 5-aminoquinoline. 6-bromoquinoline is prepared by heating p-bromoaniline with glycerol, concentrated sulfuric acid, and p-bromonitrobenzene. 7-bromoquinoline was prepared by diazotization of 7-aminoquinoline. 8-Bromoquinoline is prepared by heating o-bromoaniline, glycerol, concentrated sulfuric acid and o-bromonitrobenzene. Purpose: As an organic synthesis reagent. |
