Application

Bis[(tetrabutylammonium iodide)copper(I) iodide] can be used as a catalyst:
  • To synthesize 1,4-disubstituted 1,2,3-triazoles via three-component click reaction[1].
  • For the N-arylation of indoles in the presence of potassium carbonate as a base[2].
  • In the Ullmann coupling reaction in the presence of cesium carbonate and acetonitrile[3].
