An efficient and practical synthesis of various aryl tetrafluoroethyl ethers by the reaction of phenols with 1,2-dibromotetrafluoroethane and the subsequent reduction with zinc dust was described. The nucleophilic substitution of 1,2-dibromotetrafluoroethane with phenols initiated by bromophilic attack was improved by using Cs2CO3 as a base and DMSO as a solvent.
描述了通过苯酚与1,2-二溴四氟乙烷反应并随后用锌粉还原而有效和实用地合成各种芳基四氟乙基醚的方法。通过使用Cs 2 CO 3作为碱和DMSO作为溶剂,改善了由亲油性攻击引发的苯酚对1,2-二溴四氟乙烷的亲核取代。
