A　series　of　well-defined　copper(I)　fluoroalkoxide　complexes,　[(phen)2Cu][OCH2RF],　have　been　shown　to　undergo　trifluoroethoxylation,　pentafluoropropoxylation,　and　tetrafluoropropoxylation　with　aryl　and　heteroaryl　bromides　to　generate　the　corresponding　trifluoroethyl,　pentafluoropropyl,　and　tetrafluoropropyl　(hetero)aryl　ethers　in　good　to　excellent　yields.　The　reaction　tolerates　a　variety　of　functional　groups　and　demonstrates　efficient　scalability　and　practicality.　©　2015　Georg　Thieme　Verlag　Stuttgart.　New　York.
