1-Phenyl-2-Nitropropene (P2NP) is a representative of fatty aromatic unsaturated nitro compounds. Externally, it is a yellow needle-shaped crystals with a peculiar smell. It irritates the mucous membranes, leaves difficult-to-heal ulcers on the skin. Phenylnitropropene is highly CH-acidic.

1-Phenyl-2-nitropropene (phenyl-2-nitropropene, phenylnitropropene) has found application in fine organic synthesis, in particular the synthesis of phenyl-2-propanol, phenyl-2-propanol oxime, phenyl-2-nitropropane, and others. Can also be used in the manufacture of pharmaceuticals.
Nitropropene (chemical reference)
Somewhat later, by the step hydrogenation of furylnitroethylene was reduced to 1-furyl-2-aminoethane. According to patent data, 1-phenyl-2-nitropropen-1 by treatment with sodium amalgam in an alcohol-acetic acid medium was immediately converted into 1-phenyl-2-aminopropane, isolated as a salt.
The addition of acetylene to nitromethane leads to 1-nitropropene. In this case, the primary condensation product is considered to be 3-nitropropene, which then undergoes a rearrangement, moving the double bond to a position that ensures its conjugation with the nitro group.
Nitro-olefins, in turn, can undergo various transformations, for example, they can be reduced to the corresponding 1-phenyl-2-nitropropen-1 amines by hydrogenation in the presence of a Raney nickel catalyst, yielding the corresponding amine in 40% yield  From y-nitrostyrene by hydrogenation in the presence of platinum oxide, p-phenethylamine can be obtained in 93% yield, and 3,4-methylenedioxy-nitrostyrene and 3-nitrosy nitrostyrene in the presence of the same catalyst are hydrogenated to the corresponding amine 17.
