Acetic Acid → 2-Oxopropanal phenylhydrazone

Participants

Reaction Steps

To a solution of phenylhydrazine (10.0 g, 92.5 mmol) in water (30 mL) was added acetic acid (8.8 mL) followed by the dropwise addition of pyruvaldehyde (16.7 g, 92.5 mmol) in water (400 mL) over a 15 minute period. The solution was stirred at room temperature overnight. The reaction was filtered and the resultant solid was washed with water (2×30 mL) to provide 2-oxopropanal phenylhydrazone as a yellow solid (15.2 g, 101%).
