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.
