Ru[μ-(η5-C4H4BR)Co(η5-C4H4BR)]2 (XXI). The monofacially bound η5-borole ligands in VIIb and VIIIb shows regiospecific H/D exchange, at the α position of the boron, on treatment with CF3CO2D at room temperature. VIIb undergoes a Friedel-Crafts substitution to give the 2-acetyl derivative XXIV with MeCoCl/SnCl4 in CH2Cl2 at room temperature.
