Product 1

HCID 117688574-AllyoxystyreneYield 66%

Procedure

The reaction described in Example 1 was repeated on the same scale but with the reaction temperature maintained at ambient (23° C.), rather than 10° C., during the addition of 4-acetoxystyrene and allyl bromide. In this case, 4-allyloxystyrene was obtained in 66 % yield following vacuum distillation.
