A process for producing a p-hydroxyneophyl m-phenoxybenzyl ether represented by the general formula (II) ##STR1## (X.sub.1 and X.sub.2 are independently a hydrogen atom or a halogen atom) by subjecting a corresponding p-alkoxyneophyl m-phenoxybenzyl ether represented by the general formula (I) ##STR2## (R represents a lower alkyl group, and X.sub.1 and X.sub.2 have the same definitions as above) to ether cleavage, in which process the ether cleavage reaction is effected in an aprotic polar solvent, using a lower alkoxide of an alkali metal or an alkaline earth metal or using a metal hydroxide in the presence of a lower alcohol.

Process for producing p-hydroxyneophyl m-phenoxybenzyl ether

A higher yield of the difluorohalomethoxybenzene produced by the reaction of a metal phenolate with dibromodifluoromethane or bromochlorodifluoromethane can be obtained by conducting the addition of a metal alcoholate or a metal hydride as a reaction initiator to a solution or a suspension of an aprotic polar solvent containing the metal phenolate and dibromodifluoromethane or bromochlorodifluoromethane.
