Description
Palladium-mediated transformations are dominated by Pd ()0 and Pd(II) species, whereas the reactivity of higher oxidation states such as Pd(III) and Pd(IV) are far less explored because of the low accessibility and stability of these species.[1]
Herein, we present the synthesis, characterization, and reactivity of a novel Pd(IV) - alkyl complex.
The stabilization of the Pd(IV) species through the Yb – bipyrimidine fragment [2, 3] gives rise to a complex (1) considerably more stable than its precursors (t1/2 ≈ 11 h, 20°C) allowing the study of its reactivity. The obtained results contribute to a better understanding of the reactivity of high-oxidation states Pd species showing their possible applications in redox transformations. We are particularly interested in the photochemistry of the stable Pd(IV) species and several examples will be presented.
