Production of N-substituted aromatic hydroxylamine |
| abstract |
An economic, one-step method for the production of N-substituted aromatic hydroxylamines of formula (I)R—N(OH)—C(═O)—(O)R1 (I),with hydrogen, by catalytic hydration with possibly modified hydration catalysts in an aprotic solvent and in the presence of a halogen formic acid ester and in some cases in the presence of a base. |
