Komponenten

Versuchsvorschrift

Sodium acetate (36.1 g; 0.44 mol) and hydroxylamine hydrochloride (22.0 g; 0.32 mol) were introduced into a suspension of a2 (21.5 g; 0.1 mol) in 50% strength methanol (350 ml). The reaction mixture was stirred under reflux for 1 h. When the clear solution was cooled in an ice bath, a3 was obtained as a beige precipitate which was filtered off, washed with H2O and dried under reduced pressure over P2O5.
