Procedure
The reaction described in Example 1 was repeated on the same scale but with the reaction temperature maintained in the range of 4°-6° C., rather than 10° C., during the addition of 4-acetoxystyrene and allyl bromide. In this case, 4-allyloxystyrene was obtained in 82% yield following vacuum distillation. Residual concentrations of 4-acetoxystyrene and 4-vinylphenol were 4 and 9% respectively.
