This article presents a new class of mild reagents that is capable of oxidizing palladacycle(II) complexes to high-valent palladium species, promoting the formation of C–N bonds in stoichiometric and catalytic conditions. The weak N–O bond and the extremely electron with-drawing benzenesulfonate group on the oxygen atom of the oxidant are crucial moieties to ensure the desired activity. The oxidation mech-anism could involve outer-sphere single electron transfer (SET) processes, opening the possibility for a complementary reactivity of Pd(IV) species.
