Reaction Steps
A mixture of p-hydroxybenzaldehyde (4.0 g, 33 mmoles), allyl methyl carbonate (16.0 g, 138 mmoles), 5 percent palladium on charcoal (1.3 g, 0.6 mmole palladium) and triphenyl phosphine (0.086 g, 0.32 mmole) is refluxed overnight. After removal of the catalyst and distillation (90° C., 0.6 mm Hg), 4.54 g, 85 percent of substantially pure p-allyloxybenzaldehyde is obtained.
