Synthesis of Fluoroalkyl Palladium and Nickel Complexes via Decarbonylation of Acylmetal Species

The synthesis and characterization of a series of fluoroalkyl palladium(II) and nickel(II) complexes via decarbonylation of the corresponding acylmetal species is reported. At palladium(II), labile supporting ligands such as tri -o -tolylphosphine are required to achieve decarbonylation within 30 min at 85 °C. In contrast, decarbonylation at (PPh 3 ) 2 Ni(C(O)R F )(OCOR F ) (R F = fluoroalkyl) complexes proceeds rapidly at or below room temperature.
