Source of materialTo a 25-mL sidearm flask in a dry nitrogen box were added 3-bromo-benzo [de]anthracen-7-one (2.5 mmol), diphenyl-amine (2.50 mmol), Pd(CH 3 COO)2 (0.025 mmol, Pd/Br = 1 %), tri-tertbutylphosphine (0.03 mmol), and sodium fórí-butoxide (3.0 mmol). The flask was sealed with a septum and was then moved out of the nitrogen box. o-xylene (10 mL) was injected via a syringe. The reaction mixture was heated and stirred at 120 °C under nitrogen until the reaction was completed. The reaction mixture was then cooled to room temperature, Altered through a mixture of celite and silica gel pad, and washed with dichloromethane. The fíltrate was then washed with water and dried by MgSC>4. Concentration of the filtrate on a rotary evaporator followed by washing of the solid material with methanol afforded the desired crude product. The crude product was then dried at 120 °C in a vacuum and further purified by sublimation. Red crystals were obtained by sublimation at (4...6)-10" 3 Pa for 16 h.
