Versuchsvorschrift

A mixture of 2,6-dimethylphenol (1.22 g, 10 mmoles), allyl methyl carbonate (1.40 g, 12 mmoles), 5 percent palladium on charcoal (26 mg, 0.0125 mmole paladium) and triphenyl phosphine (20 mg, 0.0375 mmole) is heated at 70° C. for 45 minutes. Filtration of the catalyst and bulb-to-bulb distillation of the residue at 120° C., 10 mm Hg gives 1.60 g of substantially pure allyl 2,6-dimethylphenyl ether, 98.7 percent yield.
