Silver difluorochloroacetate

Hr - —Cl. Chloro compounds are readily converted into bromo compounds. but the reverse reaction is difficult. Vida1 has observed transhalogenation of bromo compounds with silver difluorochloroacetate. Thus the bisbromo-niclhyl compound (1) is converted into (2) in 70% yield by reaction with 2... 

Silver difluorochloroacetate smoothly converts bromo-compounds into the chloro-analogues for example, n-octyl bromide is converted into...
