Two of the four halogenated bipyrroles recently discovered in seabird eggs and eagle liver samples have been identified by synthesis as 1,1′-dimethyl-3,3′,4,4′,5,5′-hexabromo-2,2′-bipyrrole 1 and 5,5′-dichloro-1,1′-dimethyl-3,3′,4,4′-tetrabromo-2,2′-bipyrrole 2, and the structure of the latter compound, which is the major component in the mixture, is further confirmed by X-ray crystallography.
