Reaktionsschritte
A mixture of 2.2 mL (18 mmol) of 2-chloroiodobenzene, 1.8 mL (27 mmol) of allyl alcohol, 81 mg (0.36 mmol) of Pd(OAc)2, 5.3 g (18 mmol) of Bu4NCl, and 3.8 g (45 mmol) of NaHCO3 in 50 mL of DMF is stirred under Ar2 at 30° C. for 24 h. Water is added and the mixture is extracted with EtOAc. The extract is washed with brine, dried over MgSO4, filtered and concentrated. Flash chromatography (0-50% EtOAc in hexanes) provides 2.2 g (74%) of 3-(2-chlorophenyl)propenal.
