Abstract:
Process for preparing primary amines having a cyclopropyl unit and a primary amino group bound to an aliphatic or cycloaliphatic carbon atom (amine A) by cathodically reducing oximes having a cyclopropyl unit or oxime derivatives in which the hydrogen atom in the oxime group has been replaced by an alkyl or acyl group (oxime O) at a temperature of from 50 to 100° C. in an essentially anhydrous electrolyte solution in a divided electrolysis cell.
