Clusters get the gold: Atomic gold clusters Aun (n=3–6) are very active species (sub-mol %) for gold-catalyzed carbon–carbon and carbon–heteroatom bond-forming reactions of interest in organic synthesis. The gold clusters can be formed in situ or generated ex situ and introduced into the reaction media. Salts, complexes, and nanoparticles (NPs) can be used as a starting source of gold. Ts=para-toluenesulfonyl.
