Preparation
Allyl phenyl ether is prepared by the reaction of sodium phenoxide with allyl bromide:[1]
- C6H5ONa + BrCH2CH=CH2 → C6H5OCH2CH=CH2 + NaBr
The yield is almost quantitative when the reaction is conducted in homogeneous solution using dimethoxyethane. When the reaction is conducted as a slurry in diethyl ether, the predominant product is, after acidic work-up, 2-allylphenol.
Reactions
Allyl phenyl ether converts to 2-allylphenol in the presence of acid catalysts. This conversion is an example of the Claisen rearrangement.[2][3]
