Embodiment 1
[0027] The synthetic route of organic compound 1 is as follows:
[0028]
[0029] The synthetic steps of organic compound 1 are as follows:
[0030] (1) Add raw material 1 (3.42g, 5mmol), carbazole (1.00g, 6mmol), palladium acetate (45mg, 0.2mmol) and tri-tert-butylphosphine tetrafluoroborate (0.17g) into a 250mL two-necked flask , 0.6mmol), and then NaOt-Bu (0.58g, 6mmol) was added into the glove box, and 100mL of toluene, which had been dehydrated and deoxygenated beforehand, was poured into the two-neck flask under an argon atmosphere, and reacted at 120°C for 24 hours.
[0031] (2) After the reaction solution is cooled to room temperature, the reaction solution is poured into 200 mL of ice water, extracted three times with dichloromethane, the combined organic phases are spun into silica gel, and column chromatography (dichloromethane:n-hexane, v:v, 1 :5) separation and purification to obtain 2.3g of white powder, yield 60%.
Embodiment 2
[0033] The synthetic route of organic compound 2 is as follows:
[0034]
[0035] The synthetic steps of organic compound 2 are as follows:
[0036] (1) Add raw material 1 (3.42g, 5mmol), diphenylamine (1.01g, 6mmol), palladium acetate (45mg, 0.2mmol) and tri-tert-butylphosphine tetrafluoroborate (0.17g , 0.6mmol), and then NaOt-Bu (0.58g, 6mmol) was added into the glove box, and 100mL of toluene, which had been dehydrated and deoxygenated beforehand, was injected under an argon atmosphere, and reacted at 120°C for 24 hours.
[0037] (2) After the reaction solution is cooled to room temperature, the reaction solution is poured into 200 mL of ice water, extracted three times with dichloromethane, the combined organic phases are spun into silica gel, and column chromatography (dichloromethane:n-hexane, v:v, 1: 5) Separation and purification to obtain 2.5 g of white powder with a yield of 65%.
