Embodiment 1
[0044] The synthetic route of target compound 1 is as follows:
[0045]
[0046] In the 100mL two-necked flask, add raw material 1 (2.00g, 5mmol), phenoxazine (2.2g, 12mmol), palladium acetate Pb (OAc) (90mg, 0.4mmol) and tri-tert-butylphosphine tetrafluoroborate ( t-Bu) 3 HPBF 4 (0.34g, 1.2mmol), then sodium tert-butoxide NaOt-Bu (1.16g, 12mmol) was added in the glove box, and 60mL of toluene that had been dehydrated and deoxygenated was injected under an argon atmosphere, and reacted at 120°C for 24 hours . Cool to room temperature, pour the reaction solution into 200mL ice water, extract three times with dichloromethane, combine the organic phases, spin into silica gel, and separate and purify by column chromatography (dichloromethane:n-hexane, v:v, 2:1) to obtain 1.6 g of compound 1 as a green powder, yield 53%.
[0047] 1HNMR (300MHz, CD 2 Cl 2 ,δ): 8.54(s,2H), 8.04(s,2H), 7.62-7.48(m,5H), 7.14-7.07(m,4H), 7.03-6.96(m,12H).

Embodiment 2
[0050]The synthetic route of target compound 2 is as follows:
[0051]
[0052] Add raw material 2 (2.00g, 5mmol), phenoxazine (2.2g, 12mmol), palladium acetate (90mg, 0.4mmol) and tri-tert-butylphosphine tetrafluoroborate (0.34g, 1.2mmol) in 100mL two-necked flask mmol), then sodium tert-butoxide (1.16 g, 12 mmol) was added into the glove box, and 60 mL of toluene previously dehydrated and deoxygenated was poured into the glove box under an argon atmosphere, and reacted at 120° C. for 24 hours. Cool to room temperature, pour the reaction solution into 200mL ice water, extract three times with dichloromethane, combine the organic phases, spin into silica gel, and separate and purify by column chromatography (dichloromethane:n-hexane, v:v, 2:1) to obtain 2.2 g of compound 2 as a green powder, yield 72%.
[0053] 1 H NMR (300MHz, CD 2 Cl 2 ,δ): 8.11 (s, 2H), 7.62-7.48 (m, 5H), 7.14-7.07 (m, 4H), 7.03-6.96 (m, 12H), 6.70 (s, 2H).

Embodiment 3
[0056] The synthetic route of target compound 3 is as follows:
[0057]
[0058] Add raw material 3 (2.00g, 5mmol), phenoxazine (2.2g, 12mmol), palladium acetate (90mg, 0.4mmol) and tri-tert-butylphosphine tetrafluoroborate (0.34g, 1.2mmol) in 100mL two-necked flask mmol), then sodium tert-butoxide (1.16 g, 12 mmol) was added into the glove box, and 60 mL of toluene previously dehydrated and deoxygenated was poured into the glove box under an argon atmosphere, and reacted at 120° C. for 24 hours. Cool to room temperature, pour the reaction solution into 200mL ice water, extract three times with dichloromethane, combine the organic phases, spin into silica gel, and separate and purify by column chromatography (dichloromethane:n-hexane, v:v, 2:1) to obtain 1.3 g of compound 3 as a green powder, yield 43%.
[0059] 1 H NMR (300MHz, CD 2 Cl 2 ,δ): 8.14 (s, 2H), 7.92 (d, J=6.3Hz, 1H), 7.14-7.07 (m, 4H), 7.03-6.96 (m, 13H).
