    Notes: Abstract Electrophilic mercuration of cobaltacarboranes 1,2-R2-3-Cp-3,1,2-CoC2B9H9 (1) where R = H (1a), CH2OH (1b) was studied. Dimercurated complexes containing Hg atoms bound with boron atoms in positions 9 and 12 of the dicarbollyl ligand are the main products of the reaction with strong electrophiles such as mercury acetate or trifiuoroacetate in the corresponding acids. Mercuration of1a under milder conditions,i.e., with Hg(OCOCF3)2 in CH2Cl2 or Hg(OAc)2 in a CH2Cl2-AcOH mixture, affords 9-monomercurated complexes as the main products.

    Mercuration ofB(9)-substitutedmeta- andortho-carboranes (1995)
    Springer
    Russian chemical bulletin 44 (1995), S. 724-729

    Notes: Abstract The mercuration of substituted R2C2B10H9X-9 type carboranes (where R=m-H, X= Cl, Br, I, Me; R=o-H, X=Me) was studied. It was found that mercury atoms add to the boron atoms in position 10 ofmeta-carboranes and in position 12 ofortho-carboranes,i.e., to the boron atoms adjacent to the boron atom bonded to the X substituent. Symmetrical (R2C2B10H8X)2Hg type derivatives were obtained. It was shown that they can be used as starting materials in transmetallation reactions.
