Descrizione generale

Benzotriazole is used as a synthetic auxiliary for the preparation of organic derivatives and as a corrosion inhibitors for Cu and its alloys.

Applicazioni

Benzotriazole can be used as a reactant to synthesize:
  • β-Aminocarbonyl compounds via Mannich reaction of secondary amines and aldehydes in the presence of p-toluenesulfonic acid as a catalyst.
  • Acylbenzotriazoles via thionyl chloride catalyzed reaction with nitrobenzoic acids.
  • 1-(2-Pyridyl)benzotriazole by reacting with 2-bromopyridine in the presence of toluene as a solvent.
