N-Methyl Pyrrolidone decomposition Question

N-Methyl Pyrrolidone

My question is, is it possible to remove the double bond, and then have the option to demethylate?

Suggestions?

To make pyrrolidine, pyrroline or pyrrole - right? (no, one or two cyclic double bounds?)

What would you want with those five-membered heterocycles? Detroy them to make n-butylamine maybe? Very Happy

As far as about your question, no you can't remove the double bond from a C=O, only add a H to it to make C-OH, reductively. Or even further to the CH alkane by adding more H and splitting off H2O...

(what was/is the goal with such enterprises?)

Thanks indole,

Just a basic chemistry question, as I saw it lying around in a hardware store,
Just looked very close to piperidine, which really has not got any use except if you wanted to remove the H, by boiling in H2SO4 at 300c
It's fascinating stuff, cheers

I've just found these references:
