| Abstract: | Bromination and mercuration of cobaltacarborane 1,2,4-CpCoC2B8H10 were investigated. Mercuration under mild conditions (Hg(OCOCF3)2 in CH2Cl2) afforded the only monomercurated complex containing the mercury atom at position 6. Bromination gave rise to 3-mono-, 6-mono-, or 6,9-disubstituted derivatives depending on the reaction conditions. The mercurated derivative was studied by the X-ray diffraction method. |
