Hydroxylamine → N'-hydroxy-4-phenoxybenzenecarboximidamide

Participants

Reaction Steps

In ethanol (5.0 mL), was combined 4-phenoxybenzonitrile (200 mg, 1.02 mmol) and hydroxylamine (250 μL, 4.09 mmol). The mixture was refluxed for 3 hours. The reaction was cooled and then concentrated in vacuo to give the product, which was taken to the next step without further purification (quantitative yield). 1H NMR (500 MHz, CDCL3) δ(ppm): 4.87 (2H, bs), 7.01 (2H, d, J=9.0 Hz), 7.03 (2H, dd, J=8.7, 1.1 Hz), 7.15 (2H, tt, J=7.4, 1.1 Hz), 7.36 (2H, dd, J=8.6, 7.3 Hz), 7.59 (2H, d, J=9.0 Hz). 13C NMR (125 MHz, CDCL3) δ(ppm): 118.6 (CH), 119.6 (CH), 124, 127.3, 127.6 (CH), 130.1 (CH), 152.5, 156.6, 159.3. MS (FAB+): 229 (MH+). HRMS for C13H12N2O2 (MH+): calculated: 229.0977; found 229.0977.
