Application

Acetic acid can be used as a catalyst:
  • For the solvent-free one-pot condensation of indoles with aryl or heteroaryl aldehydes to synthesize di(indolyl)methanes.
  • In the Pictet-Spengler reaction of substituted tryptamines with cyclic ketones to synthesize tetrahydrospiro-Ͱ-carbolines.
  • To synthesize trisubstituted thiazoles via domino multicomponent reaction.

It can also be used as a:
  • solvent to synthesize aryl amine-functionalized 1,3,5-triazine derivatives via aryl amination of cyanuric chloride with aromatic amines.
