Versuchsvorschrift
Under an argon atmosphere, 1-diazo-3-(4-iodophenyl)propan-2-one (13) (1.11 g, 3.88 mmol) was dissolved in anhydrous ethanol (10 mL) and cooled to 0° C. To this was added tert-butyl hypochlorite (440 μL, 3.89 mmol) and stirred for an hour at the same temperature. After concentrating under reduced pressure, the residue was purified by silica gel flash column chromatography (n-hexane/ethyl acetate═9/1) to give 1,1-diethoxy-3-(4-iodophenyl)propan-2-one (14) as a yellow oily substance (758 mg, 2.18 mmol, 56.1%).
