Visible-light irradiation of the cation [(η-C4H4BOH)Co(η-C6H6)]+ in the presence of alkyl-substituted benzenes in CH2Cl2 results in arene exchange giving [(η-C4H4BOH)Co(η-C6R6)]+ (C6R6= toluene, p-xylene or mesitylene); the structure of [(η-C4H4BOH)Co(η-mesitylene)]BF4 was confirmed by X-ray diffraction.
