Anwendung
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.
