Really these reactions would not take place or the products would just fall apart.
Just because you can write a structure does not mean that it can exist.
If chlorine is passed into methanol, a dangerously sensitive/unstable explosive, methyl hypochlorite CH3OCl, can form. It is not possible to have a
hydroxyl group on the same carbon atom as a chlorine atom. The "CCl3OH" would immediately break apart into COCl2 and HCl. It is also generally
not possible for three methoxy, -OCH3, groups to be an the same carbon.
Neither would there be any reaction between tert-butyl alchohol, (CH3)3COH, and barium peroxide. Reacting phenol, C6H5OH, with barium peroxide would
only make barium phenolate and hydrogen peroxide.
Essentially, the answer to your question is no, it is not possible. Typically to make an organic peroxide, a ketone or aldehyde is used. I have also
remember reading something many years ago about reacting methylene chloride with sodium peroxide to make methylene peroxide, a very dangerously
sensitive explosive, but I cannot find anything about this now on the internet, and since I had first seen this my knowledge of chemistry has become
much expanded so that I have serious doubts about whether the reaction would even work. The original source was short on the details, but I think it
must have been conducted in DMSO or propylene carbonate solvent, then left for >30 days to react.turd - 4-11-2011 at 03:00
