This review summarizes Pd‐catalyzed procedures leading to single C–O bonds from aliphatic C–H bonds of substrates bearing heteroatomic groups. Coordination of the latter to PdII species favors the activation of a C(sp3)–H bond and controls the regioselectivity, leading to a palladacycle as intermediate. Either PdII–Pd0 or PdII–PdIV redox catalytic cycles, possibly with a PdIII intermediate, might be involved, depending on the directing group and the oxidant.
