Acetone → 4-(4-Methylphenyl)-3-buten-2-one

Participants

Reaction Steps

Water (20 ml) and 10% NaOH aqueous solution (4 ml) were added under stirring to the solution of 4-methylbenzaldehyde (10.2 g, 10 mmol) in acetone (10 ml). The reaction mixture was stirred for 14 hr at room temperature, then the pH value was adjusted to pH=7.0 with 10% hydrochloric acid, extracted with methylene chloride. The combined methylene chloride extract was washed with water, dried over anhydrous sodium sulfate, filtered and concentrated to give 0.73 g of a yellow viscous oil, yield: 45.6%.
