Phenol → HCID 57057502, compound

Reaction Steps

O-propenylphenol (67 g) was added to a stirred suspension of potassium carbonate (138 g) in dry acetone. Allyl bromide (67 g) was then added dropwise over about 20 minutes and the stirred mixture was heated under reflux for 4 hours. After this time, gas liquid chromatography indicated that the phenol had been converted to about 95% of a mixture of cis and trans 2-allyloxy-1-propenylbenzene. The mixture was filtered and the solvent removed under reduced pressure. The residue was vacuum distilled and yielded 58.9 g of almost pure 2-allyloxy-1-propenylbenzene which was identified spectroscopically. [b.p. 64-88° C. at 0.6 mbar].
