I don`t know,
can you build a peroxide of a anhydride ?
f.i.

bezenehexacarboxylic acid trianhydride triperoxide

Thanks

I have not been able to find any reference to methods for obtaining peroxides of carboxylic acid anhydrides. They definitely exist though, e.g. benzoyl peroxide, which is an explosive.

Acetone can absorb gaseous oxygen to form an explosive peroxide. Also, alkenes can absorb O2 to form peroxides and epoxides.

Not my field, but I think that would be a novel synthesis for acetone peroxide.

The interaction of hydrogen peroxide with acid anhydrides produces broken glassware, loud noises, blinded experimenters and (sometimes) peroxy anhydrides.

You can just about do this with benzoic anhydride and get away with it. I think the tris peroxy product you suggested would be too unstable to isolate.

IIRC, this has been discussed over at EW with acetone and O<sub>3</sub>, and not O<sub>2</sub>.
