Procedure

To a mixture of 2-ethoxyethanol (95 mL) and water (25 mL) were added 11.0 g (42.4 mmol) of 2-(2′-methylbiphenyl-3-yl)pyridine and 7.9 g (21.2 mmol) of IrCl3. The reaction mixture was heated under a nitrogen atmosphere at reflux for 50 h and cooled. The yellow precipitate that formed was collected by vacuum filtration and washed with methanol and ethyl acetate to give 11.0 g (70%) of chloro-bridged dimer
