Reaction Steps

Bu4NBr (2.0 g, 6.3 mmol), K2CO3 (7.8 g, 56.7 mmol), Pd(Oac)2 (250 mg, 1.1 mmol) and styrene (20 mL, 175 mmol) were stirred for 5 min under nitrogen. To the mixture was added 3,5-dibromobenzaldehyde (5.0 g, 18.9 mmol) in dry DMF (5.0 mL), and the mixture was stirred at 65° C. for 16 h. The reaction mixture was diluted with ethyl acetate (20 mL) and the solution filtered. The filtrate was diluted with water and extracted with ethyl acetate (3×50 mL). The organic layers were combined, dried over MgSO4, and concentrated under vacuum. To the residue was added a mixture of toluene/petroleum ether (1:1) (50 mL) and 3,5-distyryl-benzaldehyde (4.95 g, 85%) was isolated by filtration.
