This protocol avoids the gold(iii) chloride bond activation pathway commonly employed to access these functionalities. For example exposure of [LAu(iii)L′]OTf (L = N,N,N-terpyridine, L′ = 4-DMAP) to RH (R = OCH , OAc, Ph-) results in the facile formation of the corresponding functionalised gold(iii) complexes [LAu(iii)R]OTf.
