Application

Bismuth(III) iodide or Bismuth triiodide are nontoxic and hence they are used as environmentally friendly catalysts. It can be used as a catalyst in the:
  • Chemoselective deprotection of acetals and ketals in water.
  • Synthesis of polysubstituted guanidines by guanylation reaction of thioureas with amines.
  • Sulfenylation of carbonyl compounds.
