SYNTHESIS OF HETEROCYCLES ON THE BASIS OF ARYLATION PRODUCTS OF UNSATURATED COMPOUNDS. 19. ARYLATION OF 2 ACETYLTHIO- PHENE AND THE SYNTHESIS OF 2-(5-ARYL-2-THIENYL)-4-QUINOLINECARBOXYLIC ACIDS

The reaction of 2‑acetylthiophene with acetylthiophene with arenediazonium chlorides in the presence of cupric chloride as catalyst gives 2‑acetyl-5-arylthiophenes. These products react with 5-chloro- and 5-bromoisatins to give 6-chloro- and 6-bromo-substituted 2-(5-aryl-2-thienyl)-4-quinolinecarboxylic acids.
