BY-PRODUCTS OF THE AQUEOUS HALOGENATION OF AMINO DERIVATIVES

(N-X)-compounds formed upon water halogenation suffer further reaction s to yield several substances. In near neutral or mild basic condition s (N-X)-alpha-amino acids and (N-X)-amines decompose to yield aldehyde s and/or ketones, ammonia and I or primary amines, carbon dioxide (in the case of (N-X)-alpha-amino acids) and halide ions. (N-X)-peptides a lso yield ammonia under these conditions. (N-X)-alpha-amino acids deco mpose to alpha-keto acids, ammonia or primary amines and halide ions i n basic medium. The different yields for these reactions are presented .
