[0030] The preparation method of the fluoroboron dipyrrole derivative containing six trifluoromethyl groups comprises the following steps:
[0031] (1) Compound , Add it to 100 mL of anhydrous dichloromethane at a molar ratio of 1:2.5, then add a drop of trifluoroacetic acid (TFA), and stir overnight at room temperature under nitrogen protection; Benzoquinone (DDQ) was dissolved in 150 mL of dichloromethane, and then added to the reaction solution, and the resulting mixture was stirred at room temperature for 4 h; triethylamine (Et 3 N, 12 mL) and boron trifluoride diethyl ether (BF 3 ·Et 2 O, 12 mL) were slowly added dropwise to the above mixture, and stirred overnight at 0 °C; 3 The solution and water were washed twice, and the combined organic layers were washed with anhydrous Na 2 SO 4 After drying, it was spin-dried under reduced pressure; using dichloromethane-petroleum ether (1:2, v / v) as eluent, purified by silica gel column chromatography to obtain compound 1 ...
