<P>A synthetic method for 2-bromoimidazoles is developed from Rh-catalyzed cyclization of <I>N</I>-sulfonyl-1,2,3-triazoles with bromocyanides. Cu-catalyzed [3 + 2] cycloaddition followed by Rh-catalyzed cyclization starting from alkynes, <I>N</I>-sulfonylazides, and bromocyanides is also demonstrated for <I>de novo</I> synthesis of 2-bromoimidazoles in one pot. Moreover, this work was successfully employed to introduce diverse functional groups to the 2-position of imidazoles <I>via</I> cross-coupling reaction.</P><P><B>Graphic Abstract</B>
