preparation example 1
[0083] [Preparation example 1] compound (1) (chemical formula 1: R 1 = R 2 = 2-naphthyl, R 3 = R 4 = R 5 = R 6 = phenyl) preparation
[0084] 2,6-Dichloroanthraquinone (1.0 g, 3.6 mmol) and diphenylamine (1.3 g, 7.7 mmol) were dissolved in anhydrous toluene, and palladium acetate (Pd(OAc) 2 ) (2.4g, 24.4mmol), tri-tert-butylphosphine (P(t-Bu) 3 ) (0.2 mL, 1.9 mmol) and sodium tert-butoxide (t-BuONa) (0.93 g, 9.7 mmol). The resulting mixture was heated to reflux at 110°C for 3 days. When the reaction was complete, 10 mL of distilled water was added, and the mixture was stirred for 30 minutes. The resulting solid was filtered off, washed with solvents such as acetone and THF, dried and recrystallized from dichloromethane to give bis(2,6-diphenylamino)anthraquinone (1.1 g, 2.0 mmol, yield: 56 %).
[0085]A solution of 2-naphthyllithium in diethyl ether (5 mL) previously prepared by using diphenylamine (0.74 g, 4.4 mmol) and n-butyllithium (n-BuLi) (1.8 mL, 4.5 mmol, 2.5...
preparation example 2
[0089] [Preparation example 2] compound (2) (chemical formula 1: R 1 =R 2 =R 3 =R 5 = 2-naphthyl, R 4 =R 6 = phenyl) preparation
[0090] Repeat the same process as described in Preparation Example 1, but use N-phenyl-2-naphthylamine (1.7g, 7.8mmol), thereby obtaining compound (2) (0.53g, 0.61mmol, total yield: 17 %).
[0091] 1 H NMR (200MHz, CDCl 3 ): δ6.45(d, 4H), 6.6(t, 2H), 6.75-6.8(m, 8H), 7.0-7.15(m, 6H), 7.2-7.3(m, 6H), 7.45-7.6(m , 10H), 7.65-7.8(m, 6H), 7.9(s, 2H)
[0092] MS / FAB: 864 (measured value), 865.10 (calculated value)
preparation example 3
[0093] [Preparation example 3] compound (3) (chemical formula 1: R 1 =R 2 = 2-naphthyl, R 3 =R 5 = 1-naphthyl, R 4 =R 6 = phenyl) preparation
[0094] Repeat the same process as described in Preparation Example 1, but use N-phenyl-1-naphthylamine (1.7g, 7.8mmol), thereby obtaining compound (3) (0.41g, 0.47mmol, total yield: 13 %).
[0095] 1 H NMR (200MHz, CDCl 3 ): δ6.45(d, 4H), 6.5(d, 2H), 6.6(t, 2H), 6.75-6.8(m, 4H), 7.0-7.05(m, 4H), 7.15-7.2(m, 4H ), 7.3-7.35(m, 8H), 7.55-7.8(m, 14H), 7.9(s, 2H)
[0096] MS / FAB: 864 (measured value), 865.10 (calculated value)
