Phosphane and N‐heterocyclic carbene ligated gold(I) chlorides can be effectively activated by Na[Me 3 NB 12 Cl 11 ] ( 1 ) under silver‐free conditions. This activation method with a weakly coordinating closo ‐dodecaborate anion was shown to be suitable for a large variety of reactions known to be catalyzed by homogeneous gold species, ranging from carbocyclizations to heterocyclizations. Additionally, the capability of 1 in a previously unknown conversion of 5‐silyloxy‐1,6‐allenynes was demonstrated.
