Application

Potassium azide can be used as a reagent to synthesize:
  • 3-O-(3-Azidoopropyl)estrone from 3-O-(3-methanesulfonyloxypropoxy)estrone via nucleophilic azidation in the presence of imidazolium catalyst.
  • Azido phenacyl derivatives from α-bromoacetophenone derivatives in the presence of tetrabutylammonium bromide as a catalyst.
  • 1-Azido-4-fluorobenzene from potassium (4-fluorophenyl)trifluoroborate in the presence of cupric triflate as a catalyst.
