Phosphane and N-heterocyclic carbene ligated gold(I) chlorides can be effectively activated by Na[Me3NB12Cl11] 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 carbocyclization to heterocyclization. Addnl., the capability of Na[Me3NB12Cl11] in a previously unknown conversion of 5-silyloxy-1,6-allenynes was demonstrated. The synthesis of the target compounds was achieved using sodium undecachloro(methanamine)dodecaborate as anion source and (triphenylphosphine)gold chloride, [[(1,1′-biphenyl]-2-yl)bis(1,1-dimethylethyl)phosphine](chloro)gold [Au(JohnPhos)cl], [μ-Bis(diphenylphosphino)methane]dichlorodigold, [1,3-Bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene](chloro)gold as catalysts.
