Komponenten

Versuchsvorschrift

Ethyl 3-(4-iodophenyl)-3-oxopropanoate (3.0 g, 9.4 mmol) was added slowly to a solution of hydroxylamine hydrochloride (660 mg, 9.44 mmol), NaOH (795 mg, 19.8 mmol), and water (12 mL) at 0° C. The reaction mixture was kept at 0° C. for 1 h. The precipitate was collected by filtration, rinsed with water, and dried under vacuum to afford the title compound as white solid (2.0 g, 64%). 1H NMR (CDCl3, 400 MHz): δ 7.84 (d, 2H), 7.40 (d, 2H), 3.78 (s, 2H). 13C NMR (acetone-d6, 100 MHz): δ 176.1, 164.6, 139.1, 129.2, 129.0, 98.6, 34.4.
