Abstract
The direct halodefluorination of perfluoroacyl fluorides holds considerable interest in both synthetic and theoretical studies. However, the great strength of the C-F bond at the carbonyl carbon atom in comparison with the analogous C-Cl and C-Br hinders such transformations [1, 2]. In the case of iododefluorination, such reactions have not even been reported.
