MEKP Reaction Mechanism

Gooferking Science - 2-6-2014 at 05:39

I was recently wondering what the reaction mechanism is when MEKP is made. Is it complicated, or do the MEK molecules just simply bond together with the hydrogen peroxide? I looked it up, and I couldn't find anything on the subject. The method I use to make MEKP is the MEK + hydrogen peroxide + HCl. The acid is just a catalyst, right? Sorry if this is a noob question, but I couldn't find anything about it.

Yes, the acid is just a catalyst. I know little on the subject, but it appears hydrogen should be released in the reaction. Is this so?

Consider this: once you protonate MEK, you now have an electrophilic center at your carbonyl carbon, which can now react with your hydrogen peroxide. Would you now be able to write a plausible mechanism based on this hint?

Hydronium ions, sure, but certainly not hydrogen, unless something else magical is happening behind the scenes.

Sorry, mindless speculation, as normal in my O. Chem posts.
