Participants

Reaction Steps

Tetralone (25 g, 171 mmol) was added to a solution of potassium tert-butoxide (22 g, 196 mol) and isoamyl nitrite (26 g, 222 mmol) in diethyl ether (200 ml) and tert-butanol (200 ml). The solution was stirred at room temperature for 4 hours and then filtered to collect the potassium salt of the oxime. The solid was dissolved with 1 N aqueous hydrochloric acid (200 ml) and extracted with chloroform and dried over anhydrous magnesium sulfate. After removal of the solvent, the residue was washed with ethyl acetate, and dried to give 3,4-dihydro-[1,2]naphthoquinone 2-oxime (21.5 g, 123 mmol, 72%) as brown crystals.
