Abstract
2-Azido-2,2-difluoroethanol is useful in the preparation of energetic placizers for explosives and propellants. Ethyl 2-bromo-2,2-difluoroacetate reacts with sodium azide to produce ethyl 2-azido-2,2-difluoroacetate which then reacts with sodium borohydride in water to produce the 2-azido-2,2-difluoroethanol.
