potassium azide Chemical Properties,Usage,Production
Chemical Properties
colorless; body-center; tetr, a=0.6091 nm, c=0.7056 nm [CIC73] [CRC10]
Solubility (water) (0°C) 41.1 g, (17°C) 49.6 g, (100°C) 105.7 g/100 g H2O; (alcohol, 16°C) 0.137 g/100 g absolute alcohol; insoluble in ether.
Uses
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.
