A chemoselective C(sp 2 )F or C(sp 3 )F bond activation of hexafluoropropylene (HFP) was achieved by adopting the proper combination of a Lewis acid co‐additive with a ligand which coordinates Pd 0 . The treatment of [(η 2 ‐HFP)Pd(PCy 3 ) 2 ] with B(C 6 F 5 ) 3 allowed a chemoselective C(sp 3 )F bond cleavage of HFP to give a unique cationic perfluoroallypalladium complex. In this complex, the coordination mode of the perfluoroallyl ligand was considered to be of the unique η 2 ‐fashion.
