Regioselective B(3)–H bond activation based on an o-carboranyl dithiocarboxylate ligand and its derivatives

Using methyldithiocarboxyl as the directing group, together with [Cp*IrCl₂]₂, selective B(3)–H activation occurs at o-carborane. A series of substitution complexes have been prepared from the B(3)–H activated complex.
