The oxidation of alkyl or benzyl N-hydroxycarbamate produced mainly the corresponding O- alkoxycarbonyl or O-benzoxycarbonyl N-hydroxycarbamates and small amounts of the corresponding trisubstituted hydroxylamines. The oxidation of sodium benzhydroxamate with iodine gave O-benzoyl benzhydroxamate; hydroxyurea and N-hydroxy-N′-phenylurea were similarly converted into N-carbamoyloxyurea and N-hydroxy-N′-phenyl-N- ...
