应用
(IMes)-copper complex catalyzed methylenation of cinnamaldehydes
Typical procedure (R = H):
To a solution of (IMes)-Cu complex catalyst (20.2 mg, 0.050 mmol) and triphenylphosphine (288 mg, 1.10 mmol) in dioxane (10 mL) at 25 °C is added 2-propanol (84 µL, 1.1 mmmol) followed by trans-cinnamaldehyde (125 µL, 1.00 mmol) and the trimethylsilyldiazomethane solution (1.4–2.0 mmol) under inert atmosphere. The resulting mixture is then heated at 60 °C for 2 h. Afterward, 3% H2O2 (10 mL) is added and the organic layer is extracted with ether (3 x 20 mL). The combined organic layers are washed with brine (2 x 20 mL) and dried over MgSO4. The filtrate is removed under reduced pressure and the residue is purified by flash chromatography on silica gel (eluent: 1% EtOAc/hexanes) to give 1-phenyl-1,3-butadiene (100 mg, Y.77%) as a colorless oil.
