This is not a reduction procedure, but I didn't want to open new thread for posting this synthesis. It is an ordinary synthesis for obtaining 1-phenyl-2-nitropropene. I haven't found the below reference in TFSE so I assume it hasn't been posted before.
1-phenyl-2-nitropropene
A solution of benzaldehyde (6.4g, 60 mmol) and ammonium acetate (1g, 13 mmol) in nitroethane (20mL, 280 mmol) was heated to reflux for 5 h. On cooling, after removal of solvent, the residue was purified by column cromatography on silica gel 60 N (neutral; hexane/chloroform; 2:1, v/v), then recrystallized from hexane to give 1-phenyl-2-nitropropene as a light yellow crystal. Yield: 6.2g (63%), mp 71-73° C.
