YieldReaction ConditionsOperation in experiment
0.8 g With tris-(dibenzylideneacetone)dipalladium(0); johnphos; sodium t-butanolate; In toluene; at 95 - 105℃; for 6h;Inert atmosphere; Glovebox; Sealed tube; N-(2-(prop-1-en-2-yl)phenyl)-9-(pyridin-2-yl)-9H-carbazol-2-amine (2) 2-bromo-9-(pyridin-2-yl)-9H-carbazole (1.00 g, 3.0 mmol, 1.00 eq), 2-(prop-1-en-2-yl)benzenamine (0.48 g, 3.6 mmol, 1.20 eq), Pd2(dba)3 (0.14 g, 0.15 mmol, 0.05 eq), and (2-biphenyl)ditert-butylphosphine) (0.09 g, 0.3 mmol, 0.10 eq) was added to a dry pressure tube equipped with a magnetic stir bar. The tube was then taken into a glove box. t-BuONa (0.60 g, 6 mmol. 2.00 eq) and dry toluene (10 mL) were added. The mixture was bubbled with nitrogen for 10 minutes and then the tube was sealed. The tube was taken out of the glove box and heated to 95 C.-105 C. in an oil bath. The reaction was monitored by TLC and about 6 hours later the starting was consumed completely. Then the mixture was cooled to ambient temperature, diluted with ethyl acetate and washed with water. The organic phase was dried over sodium sulfate, then filtered and concentrated under vacuum. The residue was purified by silica gel column chromatography, using a mixture of hexanes and ethyl acetate as an eluent, in a ratio of 1:4 in volume and giving a white solid 0.80 g in yield of 70%. 1H NMR (400 MHz, CDCl3): δ 8.69-8.68 (m, 1H), 8.10-8.07 (m, 1H), 8.02 (d, 1H, J=7.5 Hz), 7.96 (d, 1H, J=8.5 Hz), 7.71-7.67 (m, 1H), 7.58 (s, 1H), 7.46-7.44 (m, 1H), 7.32-7.21 (m, 6H), 7.02-6.99 (m, 1H), 6.95-6.93 (m, 1H), 5.11 (s, 1H), 5.02 (s, 1H), 1.98 (s, 3H).

YieldReaction ConditionsOperation in experiment
85% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In ethanol; water; toluene; at 120℃; for 48h;Sealed tube; Inert atmosphere; Add 100 ml (60 vol) toluene, 10 ml (6 vol) ethanol to a 350 ml sealed tube.10ml (6vol) purified water,Turn on the agitation,2-bromo-9-(pyridyl-2-yl)carbazole 1.62 g (1.0 eq) was added in that order.2-borate triphenylene2.13 g (1.2 eq) of potassium carbonate 1.38 g (2.0 eq),Tetrakistriphenylphosphine palladium 289mg (0.05eq), nitrogen bubbling for 30min,After completely degassing,The temperature was raised to 120 C and kept for 48 h. System cooling,Add 100 ml of purified water, separate the layers, and extract the aqueous phase with ethyl acetate 100 ml*3 times.The organic phase is combined, dried over anhydrous sodium sulfate, dried and concentrated, and then chromatographed.Eluent EA: PE = 1:2, and the eluent was concentrated to give a white solid, 1.98 g (yield: 85%).
