      Reduction of phenyl-2-nitropropen  Bookmark   

To make this shit seems much more easy than to make an amine
out of it.
How many diffrent ways are there for someone that does not have NaBH4?
Yes I have UTFSE and I have found some methods..

1.zink/amalgam
2. palladium on carbon
3. electrolytic reduction
(does anyone know how high the yeld should be fo this?)

Maybee there are some genius here that know more?

I like the name of the author of the LAH article - F.Nord - very Illuminati-inspired.
