Can the ion bromonium be produced from NBS without HBr?
I'm trying to figure out the mechanism for this reaction NBS.png (the product is in the second image 2021-11-21 (1).png ). As far as I understand, it is an electrophilic aromatic substitution, but I don't understand how to get a bromonium ion out of the NBS. I read that the Br in an N-Br bond has a ...

God, that's true, I don't know how that slipped my mind.
Thank you so much for your help!

Re: Trying to figure out reaction mechanism for reduction of nitro group.
Do you think it would be better if in the first step the oxygen took the proton, but the other oxygen did not give its pi electrons to the positive nitrogen? That way the molecule in the second step would stay positive (due to the nitrogen's charge). The only thing is that if in the second step the ...

Trying to figure out reaction mechanism for reduction of nitro group.
Hey, I'm trying to draw the mechanism for the catalytic hydrogenation of a NO2 group with Pd/C as a catalyst. I've looked at several articles (mostly "Insights into the mechanism of nitrobenzene reduction to aniline over Pd catalyst and the significance of the adsorption of phenyl group on kine...
