ABSTRACT:
A process for manufacturing an α-dihydroxy derivative from an aryl allyl ether wherein such α-dihydroxy derivative can be used to prepare an α-halohydrin intermediate and an epoxy resin prepared therefrom including epoxidizing an α-halohydrin intermediate produced from a halide substitution of an α-dihydroxy derivative which has been obtained by a dihydroxylation reaction of an aryl allyl ether in the presence of an oxidant or in the presence of an oxidant and a catalyst.
