ChemistryOpen, Volume 15, Issue 4, April 2026.Palladium is a simple and versatile redox‐active metal that plays a crucial role in the oxidation reactions for organic synthesis and production of pharmaceutical intermediates. Notably, there has been significant progress with Lewis acids (LAs), which are non‐redox metal ions promoting Pd(II)‐catalyzed oxidation via C—H and C—C bond activation.
