Versuchsvorschrift

To a solution of 5 mL (37.5 mmole) 1-tetralone in 25 mL ethanol was added 2.7 mL (40 mmole) of 50% hydroxylamine in water. The reaction mixture was heated under reflux for 2 hrs, then stirred at room temperature for 16 hrs. The solution was concentrated under reduced pressure. The residue was recrystallized from toluene/hexane to give 1-tetralone oxime (3,4-dihydro-2H-naphthalen-1-one oxime), 3.86 g, m.p. 101-102°.
