3-Chlorobenzaldehyde → 3-Chlorobenzenecarbaldehyde oxime

関与物質

反応手順

A solution of hydroxylamine hydrochloride (3.68 g, 53 mmol) in water (5 ml) was added to a solution of 3-chlorobenzaldehyde (5.00 ml, 44 mmol) in ethanol (20 ml). A solution of sodium hydroxide (2.64 g, 66 mmol) in water (5 ml) was added. The reaction mixture was stirred at room temperature for 48 h. The reaction mixture was given onto water/ice (150 ml). The formed precipitation was isolated by filtration and dissolved in dichloromethane (200 ml). This solution was dried over magnesium sulphate. The solvent was removed to give 3.88 g of 3-chlorobenzaldehyde oxime, which was used without further purification.
