Abstract

The ability of gold-hydroxides to fix CO₂ is reported. [Au(IPr)(OH)] and [{Au(IPr)}₂(μ-OH)][BF₄] react with atmospheric CO₂ to form the trigold carbonate complex [{Au(IPr)}₃(μ³-CO₃)][BF₄]. Reactivity studies revealed that this complex behaves as two basic and one cationic Au centres, and that it is catalytically active. DFT calculations and kinetic experiments have been carried out.
