What substance can gold react with?

Gold can react with superacid, for example:

The proportion of aqua regia, concentrated hydrochloric acid and concentrated nitric acid is 3: 1, and the product contains HAuCl4, that is, tetrachloroauric acid.

Super aqua regia is to replace hydrochloric acid in aqua regia with hydrogen fluoride, that is, to replace HCl with HF.

Magic acid, HSO3F*SbF5, is made of concentrated sulfuric acid, concentrated hydrofluoric acid and antimony oxide in a certain proportion. It is the strongest acid found so far. Because it is unstable and can react with most substances, it is necessary to prepare now.

These three kinds of superacids are familiar to everyone, and I won't introduce many superacids.
