A cyclic peroxide from urea?
I was wondering if a cyclic peroxide could be prepared from urea as a cyclic peroxide can be prepared from acetone. I'm aware that urea forms salts,
but I doubt that would prevent this reaction from proceeding. Can someone enlighten me?
I weep at the sight of flaming acetic anhydride.

I don't think so
Not unless you have a bis-dialkylamino urea, like for example N,N,N,N-bis-dimethylurea, O=C{N(CH3)2}2
I think unless you have tertiary amines in the urea, the peroxyl will isomerize to an iminol, which just rearranges back to the urea, or maybe
dehydrates to a nitrile (unlikely).
Since tertiary amines cannot form imines, this would prevent such isomerization from occurring.

I tried it earlier today - didn't work.

Urea can cocrystallize with hydrogen peroxide in a 1:1 ratio, forming white crystals solid at room temperature. This is sometimes called "carbamide
peroxide", though I do not think it is actually ionic.

What about acetamide? Also why HMTD cannot form nitrate salt or similar?

well HMTD is made from hexamine, in which can be made into hexamine chloride by addition of HCl
also hexamine di nitrate can be made by reacting it with HNO3, this doesnt take high percentages, also
dont know about carbonates, and neither see much reason for it anyways

Do you say that HMTD reacts with acids to give just hexamine salts? I meant HMTD nitrate, as it's also an amine.

I guess the N-H bond tends to form salts sometimes. I won't be writing for a while, it won't be because I've blown myself up with AP.
