Gold(III) acetate

Gold(III) acetate, also known as auric acetate, is a chemical compound of gold and acetic acid. It is a yellow solid that decomposes at 170 °C to gold metal. This decomposition of gold(III) acetate has been studied as a pathway to produce gold nanoparticles as catalysts.^[3]

Production and reactions

Gold(III) acetate can be produced by the reaction of gold(III) hydroxide and glacial acetic acid:^[4]

Au(OH)₃ + 3CH₃COOH → Au(CH₃COO)₃ + 3H₂O

It reacts with 2-(p-tolyl)pyridine (tpy) in presence of trifluoroacetic acid to form Au(CF₃COO)₂(tpy).^[5]

Gold(III) sulfide has been claimed as the product when gold(III) acetate is sonicated with cyclo-octasulfur in decalin.^[6]
