Summary: | Synthesis of perfluoroalkoxylated (hetero)arenes (Ar–OR
F
) from readily available perfluoroalkyl iodides (R
F
–I) through photocatalytic selective O–R
F
bond formation.
Development of an efficient process that employs commercially available and cost effective reagents for the synthesis of perfluoroalkoxylated aromatic compounds (Ar–OR
F
) remains a daunting challenge in organic synthesis. Herein, we report the first catalytic protocol using readily available perfluoroalkyl iodides (R
F
I) and
N
-(hetero)aryl-
N
-hydroxylamides to access a wide range of perfluoroalkoxylated (hetero)arenes. Mild reaction conditions allow for selective O–R
F
bond formation over a broad substrate scope and are tolerant of a wide variety of functional groups. Mechanistic studies suggest the formation and recombination of persistent
N
-hydroxyl radicals and transient
R
F
radicals under photocatalytic reaction conditions to generate N–OR
F
compounds that rearrange to afford the desired products. |
