Perfluorobenzyl bromide reacts readily with acid-washed cadmium powder in DMF at room temperature to give the F-benzylcadmium reagent. Metathesis of the F-benzylcadmium reagent with Cu(I)Br at -40-degrees-C to -35-degrees-C in DMF affords the F-benzylcopper reagent. The formation of the F-benzylcadmium and -copper reagents was confirmed by F-19 NMR spectral analysis of the reaction mixture and chemical transformations.
