EXAMPLE - Under inert conditions, 22.7 g (210 mmole) sulfur tetrafluoride (SF4) were condensed in a bomb tube containing 23.1 g (100 mmole) 1-azabenzanthrone. The reaction mixture was heated at 180degreesC for 10 hours. After expelling excess SF4, the brown residue was recrystallized twice from dioxane/ethanol (4:1), giving about 99.0% pure 7,7-difluorodibenzo(de,h)quinoline (IIA) in a yield of 18.3 g (72.3 mmole; 72.3% of the theory). A mixture of 15.20 g (60 mmole) (IIA) and 4.90 g (10 mmole) iridium(III) acetylacetonate, suspended in 200 ml ethylene glycol, was stirred at 165degreesC for 140 hours. The reaction mixture was cooled to room temperature, treated with a mixture of 160 ml ethanol and 40 ml 1 N hydrochloric acid (HCl) and stirred for 20 minutes. The deep red, finely crystalline precipitate was filtered, washed with 4 x 50 ml ethanol/1 N HCl (4:1), 4 x 50 ml ethanol/water (4:1) and 4 times with ethanol, then dried in vacuo. High vacuum sublimation gave about 99.8% pure fac-tris(7,7-difluorodibenzo(de,h)quinoline-C2,N)iridium(III) in a yield of 7.80 h (8.2 mmole; 82.2% of the theory).
