as chlorinating agents and oxidants. 1 Their properties are similar to those of N-chloroamines, which, however, are less stable. A few of them are also common- ly used as chlorinating reagents and oxidants in organic synthesis: since chloroamines are easier to handle than chlorine gas or metal hypochlorites, they are widely used in organic synthesis in addition to their use in the purifi- cation of water

A simple and effective method for the synthesis of N,N-dichloroamines from primary amines was conducted successfully with m-CPBA as oxidant and FeCl3 as chlorine source at 0 °C. Moreover, N,N-dichloroamines could be converted into nitriles or N-chloroimines in good yields.
ABSTRACT A mild and efficient method for preparation of N-chloroamines by oxidative N-halogenation of primary/secondary amines using oxone-KCl is described. GRAPHICAL ABSTRACT
