A series of well-definedcopper(I) fluoroalkoxidecomplexes, [(phen)2Cu][OCH2RF], have been shown to undergo trifluoroethoxylation, pentafluoropropoxylation, and tetrafluoropropoxylation with aryl and heteroarylbromides to generate the corresponding trifluoroethyl, pentafluoropropyl, and tetrafluoropropyl (hetero)aryl ethers in good to excellent yields. The reaction tolerates a variety of functional

most solvents undergo unimolecular heterolysis to give singlet aryl cations which are captured by solvent. This mechanism is dominant for arenediazonium ions without electron-withdrawing substituents in all solvents, and the only reaction observed in water. Additionally, appreciable yields of fluoroarenes are obtained by fluoride abstraction by the aryl cation from fluorinated solvents and from tetrafluoroborate

reactions such as aryl fluorides activated with either a bromide or a chloride substituent were aptly converted to corresponding ether products at 25 °C. This reaction would potentially be useful to link an alcohol to an additional functional group through further chemical transformations via the use of a residual bromide or chloride substituent.
Copper(I) fluoroalkoxidecomplexes bearing dinitrogen ligands were synthesized and the structure and reactivity of the complexes toward trifluoroethoxylation, pentafluoropropoxylation, and tetrafluoropropoxylation of aryl and heteroarylbromides were investigated.
