Controversy resolved! A combination of gas‐phase ion–molecule reactions and theoretical studies confirm bisligated mononuclear Au I complexes are unable to undergo oxidative addition of iodobenzene for Sonogashira coupling, but that the ligated gold clusters [Au 3 L n ] + (L=Ph 2 P(CH 2 ) n PPh 2 ; n =3–6) activate the CI bond. DFT calculations on the transition states show that the linker size n tunes the cluster reactivity.
