Production and reactions

Chloryl tetraperchloratoaurate is produced by the oxidation of gold metal, gold(III) chloride, or chloroauric acid by dichlorine hexoxide:[1][2]

2 AuCl3 + 8 Cl2O6 → 2 [ClO2][Au(ClO4)4] + 6 ClO2 + 3 Cl2

A production of gold(III) perchlorate is attempted by heating this compound, but it instead forms an oxy-perchlorato derivative.[1]
