实验步骤: At 60° C., a solution of 12.0 g (0.03 mol) of tetrakis(diethylamino)phosphonium bromide in 12 g of N-methylpyrrolidone (NMP), 174.3 g (3 mol) of potassium fluoride, 4.1 g (0.03 mol) of nitrotoluene and 18 ml of xylene are successively added to 421.7 g (3 mol) of 4-chlorobenzaldehyde (4-CBAL). The reaction mixture is dried by azeotropic distillation of the xylene under reduced pressure. After 24 hours at 1 90° C., the formation of 4-fluorobenzaldehyde (4-FBAL) and of benzaldehyde produced by dehalogenation, and the conversion of the reaction are determined by gas chromatography. The reaction mixture is dried by azeotropic distillation of the xylene under reduced pressure
