Nitroethane → 2,4-Dichloro-1-(2-nitro-1-propen-1-yl)benzene

Participants

Reaction Steps

A mixture of 2,4-dichlorobenzaldehyde (1.45 g, 8.3 mmol), ammonium acetate (0.64 g, 8.3 mmol) and nitroethane (6 g, 80 mmol) was heated under reflux for 6 hr. The mixture was allowed to cool to room temperature and ethyl acetate was added. The mixture was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated. Recrystallization from ethanol gave 2,4-dichloro-1-(2-nitro-1-propenyl)benzene (yellow needle crystals, yield; 1.0 g, 52%).
