Many C–C bond activation methods involve strain-releasing cleavage of small rings to compensate for unfavourable kinetics and thermodynamics. Now, the 1,2-positional interchange of vicinal C–C and C–Pd bonds has been reported, giving access to quaternary carbon–palladium bonds. This dyotropic rearrangement has been used for the enantioselective synthesis of functionalized fluorinated cyclopentanes.
