So i'm trying to reduce an aryl nitro compound into a primary amine (the whole compound should look like a two anilines connected by a sulfur bridge in orto position) via Fe/H+ reduction, we have some issues with my schools equipment so right now we only have IR to verify if the reduction went through.
What kind of peaks should i be looking for in the IR spectrum? According to some research i've done the whole reduction process first goes to a nitrous group, then to hydroxylamine, and then to the primary amine, how can i identify if i still have those leftovers using IR?
Also, i read somewhere that you can use Avogadro to simulate the IR spectra but i can't find how.
Thanks in advance, your help will be greatly appreciated.
