Vinyloxiranes, when treated with A -bromosuccinimide-triethylamine tris(hydrogen fluoride) at — 10 C in dichloromethane, are converted into the corresponding (bromofluoro-ethyl)oxiranes.43 The regioselectivity and yield of the reaction are dependent on the degree of substitution of the vinyl group. [Pg.240]
