Abstract

Cyanogen bromide is a versatile reagent used in organic synthesis. Under different conditions, the BrÀC bond can be cleaved in a diverse manner (Scheme 1, Modes I–IV). Thus, BrCN was shown to serve as a donor of Br+ in reactions with strongly nucleophilic organometallic reagents to provide the corresponding vinyl-or arylbromides (ModeI).[1] In the reaction with vinyltellrium bromide, cyanogen bromide acted as an equivalent of a ...
