Yield	Reaction Conditions	Operation in experiment
58%	With 2,3-dicyano-5,6-dichloro-p-benzoquinone; In toluene; for 0.333333h;Heating / reflux;	4-Bromopyrene. To a solution 4-bromo-1,2,3,6,7,8-hexahydropyrene (2.01 g, 7.0 mmol) in toluene (135 mL) DDQ (5.30 g, 23 mmol) was added in one portion, the flask was flushed with argon and the mixture was refluxed for 20 min, then cooled and filtered. The solution was washed with 10% NaOH (30mL), water (50 mL), and dried over CaCl2, then evaporated and the residue was flash chromatographed on silica gel in toluene. Yield 1.14 g (58%).
51%	With 2,3-dicyano-5,6-dichloro-p-benzoquinone; In toluene; for 0.333333h;Inert atmosphere; Reflux;	To a solution of 4-bromo-1,2,3,6,7,8-hexahydropyrene (2.01 g, 7.0 mmol) in toluene (135 mL) was added 2,3-dichloro-5,6- Dicyano-1,4-benzoquinone (DDQ) (5.30 g, 23 mmol),The flask was flushed with argon and the mixture was refluxed for 20 min, then cooled to room temperature and filtered.The solution was washed with 10% NaOH (30 mL), water (50 mL) and dried over sodium sulfate.After the ceria column separation using dichloromethane as the eluent,Pure product (1.0 g) was obtained (yield 51.0%).
