How is Gold(III) Chloride (CAS: 13453-07-1) typically synthesized?

Gold(III) chloride can be synthesized by the chlorination of gold(III) compounds or gold metal. Common methods include the reaction of gold(III) oxide with chlorine gas or by the chlorination of an aqueous gold(III) solution. The synthesis typically involves the use of a catalyst and is carried out under controlled conditions to achieve high yields and selectivity.
