Versuchsvorschrift
In a 250 ml single neck flask was charged 5.88 g (30.3 mmoles, 1.0 eq.) of 4-(1-naphthyl)-3-buten-2-one and 5.2 g (75.4 mmoles, 2.5 eq) of hydroxylamine hydrochloride and 6 g of 50% sodium hydroxide (75 mmoles, 2.5 eq) and 100 ml of methanol. The reaction mixture was stirred at reflux for 2 hours. The reaction mixture was concentrated, diluted with water (50 ml), and then extracted with ethyl acetate (2×50 ml). The organic phase was dried and concentrated, to obtain 3.9 g of 4-(1-naphthyl)-3-buten-2-one 2-oxime (E/Z mixture of isomers) as an oil in 62% yield.
