    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reducing oximes having a cyclopropyl unit or oxime derivatives in which the hydrogen atom in the oxime group has been replaced by an alkyl or acyl group (oxime O) at a temperature of from 50 to 100° C. in an essentially anhydrous electrolyte solution in a divided electrolysis cell.

    IPC: C25B3/23

    Abstract: The invention relates to a method for the electrolytic oxidative alkoxylating cleavage of 1,2-diarylethane derivatives by electrolytically oxidizing the respective 1,2-diarylethane derivative in a solvent containing the alcohol required for alkoxylation, electrolytic oxidation being performed on a diamond electrode. The inventive method makes it possible to especially produce diaryl derivatives when a 1,2-diarylethane derivative in which the two aryl radicals are directly bonded to each other is used as a substrate.
