Phosphane and N‐heterocyclic carbene ligated gold(I) chlorides can be effectively activated by Na[Me3NB12Cl11] (1) under silver‐free conditions. This activation method with a weakly coordinatingcloso‐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 of1in a previously unknown conversion of 5‐silyloxy‐1,6‐allenynes was demonstrated.
