Abstract

Manufacture of N-arylglycinonitriles by reacting N-arylamines with carbonyl compounds and hydrogen cyanide under specific reaction conditions in respect of the temperature, reaction time and hydrogen cyanide concentration. The N-arylglycinonitriles obtainable by the process of the invention are antioxidants and valuable starting materials for the manufacture of dyes, fungicides, bactericides, textile assistants and as inhibitors for use in antifreezes.
