Water → Phenyl N-hydroxycarbamate

Participants

Reaction Steps

Phenyl chloroformate (10 g, 63.8 mmol) in ether (10 mL) was added dropwise to a stirred mixture of finely ground hydroxylamine hydrochloride (63.8 mmol, 4.43 g) and potassium carbonate (58.4 mmol, 8.07 g) in ether (10 mL) containing water (1 mL) at 0° C. The mixture was stirred at room temperature for three days, filtered, and the solvent evaporated to give the Phenyl-N-hydroxycarbamate as crystals, m.p. 99.5°-100.7° C. (9.20 g, 94%).
