A practical synthesis of aryl tetrafluoroethyl ethers via the improved reaction of phenols with 1,2-Dibromotetrafluoroethane (cas 124-73-2)

Add time:09/25/2019    Source:sciencedirect.com

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.
