Acetic acid, 2-(triphenylphosphoranylidene)-, methyl ester → methyl(E)-3-(3-butoxy-4-iodophenyl)acrylate

Participants

Reaction Steps

65.08 g (0.195 mol, 2 eq) of methyl triphenylphosphoranylideneacetate are added to a solution of 29.60 g (0.097 mol, 1 eq) of methyl-3-butoxy-4-iodobenzaldehyde in 360 ml of toluene. The reaction mixture is refluxed for 2 hours. The solvent is evaporated off and the oil obtained is chromatographed on silica gel (50/50 heptane/dichloromethane). 30.47 g of methyl (E)-3-(3-butoxy-4-iodophenyl)acrylate are obtained in the form of pale yellow crystals. Yield=87%
