Description and Uses

Tetrabutylammonium bromide (TBAB) may be used in the molten state in the following processes:

  • Synthesis of (2S)-5-(3-phenyl-2-phthalimidylpropanoylamino)isophthalic acid.
  • Synthesis of alkyl-substituted pyrroles in the absence of catalyst and organic solvent.
  • Synthesis of dithioacetals from acetals by transthioacetalisation in a solvent free environment.
  • Synthesis of polyamides (PAs) by the polymerization of terephthalic acid and diisocyanates.
  • Catalyze the addition of thiols to conjugated alkenes.
  • Dehydrochlorination of poly(vinyl chloride).
