Conclusions

  1. 1.

    The electrophilic bromination of cyclopentadienyl-(3)-1, 2-dicarbollylcobalt proceeds at the boron atoms of theπ-dicarbollyl ligand.

  2. 2.

    The bromination of cyclopentadienyl-(3)-1, 2-dicarbollylcobalt in methylene chloride, in the presence of AlCl3, gave the mono-, di-, and tribromo-substituted complexes, while the bromination of 1-methylcyclopentadienyl-(3)-1, 2-dicarbollylcobalt gave the mono- and dibromo-substituted complexes.
