2α-Bromocephem sulphones exhibit two different rearrangements in acetonitrile solution: first, the tendency for elimination of the bromine as a bromonium ion leads to its formal movement to the para position of the 7β- aromatic ring. Secondly, a bromopyrrole derivative may also form, which can possibly be attributed to an unusual Ramberg-Backlund-like rearrangement followed by bromination.
