Reaction Conditions:
in 1,2-dichloro-ethane for 1.5 h;Reflux;
Steps:
8. 2,4,6-Triphenylpyrylium tetrafluoroborate (S16)
2,4,6-Triphenylpyrylium tetrafluoroborate was prepared according to a modified literature-known procedure [18]. HBF4 etherate (23 mL, 167.60 mmol, 2.0 equiv) was added dropwise to a solution of acetophenone (10.0 g, 83.23 mmol, 1.0 equiv) and chalcone (34.40 g, 165.18 mmol, 1.98 equiv) in DCE (60 mL). After addition, the black solution was refluxed for 1.5 h. The solution was cooled to rt and Et2O was added to precipitate the product. The yellow product was filtered off, washed with Et2O, and dried under reduced pressure at 40 °C to afford 72% of pure material (23.8 g, 60.07 mmol). Spectroscopic data are in accordance with literature [19].
