Yield: 91%
Reaction Conditions:
with potassium tert-butylate in N,N-dimethyl-formamide at 0; for 1 h;
Steps:
9,10-Dibromophenanthrene (18).
To a solution of 17 (29.59 g, 59.44 mmol) in anhydrous DMF(450 mL) at 0 °C was added potassium tert-butoxide (21.65 g, 192.9 mmol). The mixture was stirred at 0 °C for 1h, before the mixture was quenched slowly with 6 M HCl (500 mL). The precipitate was filtered, washed with water (1.5 L) and MeOH (200 mL) and dried in vacuo affording 18 as a yellow solid (18.10 g, 91%). The reaction was also done on 3.02 mmol scale giving a yield of 79%. 1H NMR(500 MHz, CDCl3): δ = 8.63 (dd, J = 8.2, 1.4 Hz, 2H), 8.47 (dd, J = 8.1, 1.5 Hz, 2H), 7.70 (ddd, J = 8.2, 7.0,1.5 Hz, 2H), 7.66 (ddd, J = 8.1, 7.0, 1.4 Hz, 2H). 13C NMR (126 MHz, CDCl3): δ = 131.27, 130.36, 129.68,128.18, 127.76, 126.24, 122.84 ppm. HR-MS (APCI+ FT-ICR): m/z = 334.90806 [M+H+], calcd. for[C14H979Br2+]: m/z = 334.90655.
