Reduction of nitros to amines?

[jacknife360]

I've read that you can reduce aliphatic nitro groups to amines using HCl and an iron catalyst. What proportions are needed and is the catalyst pure iron or a salt? Does this work with eg. (nitromethyl)-benzene, or is this affected too much by the aromatic ring?

What reductor do you think will be used? Do you really think that the iron is a catalyst only? If you want to reduce -NO2 to -NH2, then you need something to reduce with.

Mate, HCl and Fe catalyst, that's all I read.
