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.
通过在含有金属酚酸盐和二溴二氟甲烷或溴氯二氟甲烷的无极性极性溶剂的溶液或悬浮液中加入金属醇盐或金属氢化物作为反应引发剂,可以获得通过金属酚酸盐与二溴二氟甲烷或溴氯二氟甲烷反应产生的二氟卤甲氧基苯的更高产量。
