摘要

The Pd(Ⅳ) species, known to be critical intermediates in homogeneous catalysis, were successfully generated on the surface of Pd nanocatalysts via oxidation with iodobenzene dichloride (PhlCl_2) or N-chlorosuccinimide (NCS). In particular, the Pd@SiO_2 yolk-shell nanocatalyst activated by PhlCl_2 showed high reactivity and superior stability to the other Pd-based catalysts for hydroalkoxylation reactions even at 25 ℃.
