Procedimiento

2.14 mmol (0.26 g) of picolinic acid was added to a room-temperature solution of 0.80 mmol 2-phenylbenzothiazole Iridium chloride dimer (1.0 g) in 60 mL of dichloromethane. The mixture was heated to reflux under nitrogen in an oil bath for 8.5 hours. The reaction mixture was cooled to room temperature, and the yellow precipitate was filtered off via vacuum. The filtrate was concentrated and methanol was added to precipitate more product. Successive filtrations and precipitations yielded about 900 mg of impure product. Emission spectrum is in FIG. 45.
