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]
