To benzaldehyde (8.52 g, 0.08 mmol) and nitroethane (4.05 g, 0.054 mol) in acid
of acetic acid (20 mL) was added ammonium carbonate (0.48 g, 5 mmol) with effervescence. Yellow solution
was claimed for reflux for 1h. The reaction mixture was cooled in a water bath,
while powdered zinc (16.3 g, 0.25 mol) was slowly added (violent reaction).
The reaction mixture was refluxed for 1 h, cooled and poured into water (200 mL). It was a mixture
basified with sodium carbonate and extracted with dichloromethane (2 x 75 mL).
The product obtained was a red oil (6.32 g) which was distilled to give l-phenyl-2-
propanone (3.17 g, 44%)
