Abstract:	A chemoselective C(sp²)? F or C(sp³)? F bond activation of hexafluoropropylene (HFP) was achieved by adopting the proper combination of a Lewis acid co‐additive with a ligand which coordinates Pd⁰. The treatment of (η²‐HFP)Pd(PCy₃)₂] with B(C₆F₅)₃ allowed a chemoselective C(sp³)? 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 η²‐fashion.
