    • A typical experimental procedure is as follows: To a suspension of ferrous sulphate (3.9g) in degassed acetic acid (30 ml) is added half of a degassed solution of sodium nitrite (2.4g) in water (14ml). After 10 min. at room temperature, a degassed solution of the isoxazolone (3.5 mmol) in acetic acid is added dropwise simultaneously with the remainder of the sodium nitrite solution over about 30 min. After a further 30 min., the mixture is diluted with water and worked up in the usual manner. The crude product is then purified by flash chromatography on silica.
