Abstract

Oxidation of Au⁰ with the synergistic Ag⁺/0.5 I₂ system in the commercial organic solvent 1,2,3,4-tetrafluorobenzene led to the perfluoroalkoxyaluminate salt of the [Au(CO)₂]⁺ cation known from superacid chemistry. This [Au(CO)₂]⁺ salt proved to be an excellent ‘naked’ Au⁺-synthon yielding complex salts with [Au(η²-P₄)₂]⁺, [Au(η¹-P₄S₃)₂]⁺ and half-sandwich [Au(η²-C₆H₆)(CO)]⁺ cation.
