The use of an air‐ and moisture‐stable dinuclear PdI complex as an efficient catalyst for the formation of C(sp2)−SeR bonds is here reported. The privileged reactivity of the PdI dimer allows for the direct use of selenolates as nucleophiles in the cross‐coupling. Although previous methodologies suffer from catalyst poisoning through the formation of Pd‐ate complexes, the mechanistically distinct dinuclear
