Excellent find, thanks Klute!
I don't know what practical use could such a reaction have, but this is the first paper I saw that describes good to excellent yields in N-oxidation
of R-CH2-NH2 type of amines to nitro compounds.

The reference was actually posted by quantum_dom in the very first post of this thread, though i guess he didn't have access to the paper.
Nicodem: "this is the first paper I saw that describes good to excellent yields in N-oxidation of R-CH2-NH2 type of amines to nitro compounds."
Here's another one (also given in the first post! The others concern oxidation of aromatic amines) using isomers of butylamine:

do you think this reaction will work for ethylamine.
it states butyl amine as the lowest alphatic amine in it examples.
would nitro ethane azeotrope with the acetone in the dioxane solution.

Can anyone help me if i have a serious problem?
The question is:
that can the phenyl-2-nitrostyrene change to phenyl-2-nitropropene with formaldehyde and if it reacts what kind of catalizator is needed or not needed
to complete the reaction?
thanks everybody

That's not possible in a one step reaction, and I highly doubt it's possible.
Addition of formaldehyde to the double bond would form 2-nitro-1-phenylpropan-3-ol ("b-(hydromethy)phenyl-b-nitroethane") . You would have to
dehydrate this to obtain the alcene, which would surely partially rearrange to the nitropropene, but both steps would surely give alot of byproducts,
polycondensations and other tar-forming reactions.

First of all thanks again Klute
Then how can I convert my phenyl-2-nitrostyrene to phenyl-2-nitropropene?

What does it produce a primary amine with H2O2? a nitroso?

An oxide, presumally. hindered secondary amines can form stable nitrosyl radicals (2,2,6,6-tetramethylpiperidine, diisopropylamine, etc..)

Him little that I have found H2O2 it oxidizes a secondary amine to hydroxilamine. It compares the activity of H2O2 with a peracid.

What are the conditions when condensing formaldehyde with phenylnitroethane ? For catalyst using some amine or base, but what if formaldehyde is in
water solution 40%? What solvent should I use ?
