The more the merrier: Following previous investigations on the synthesis of organogold complexes by using [Au(IPr)(OH)], a high-yielding straightforward methodology for the synthesis of gem-diaurated and σ,π-acetylide species via a dinuclear gold hydroxide complex [{Au(IPr)}2(μ-OH)][BF4] (see scheme) has now been developed.
