Preparation of O-substituted hydroxylamines (I) H2N-O-CH2-R (I) (R = H, organic residue) and their salts, by reacting a cyclic imidether II of a 1,4- or 1,5-dicarboxylic acid, which contains an ether group -O-CH2-R, with a basic compound by using a primary aliphatic amino alcohol III as the basic compound and optionally converting the compound I into its salts. |
