Abstract
This communication deals with a continuation of work described in the previous paper on this topic2). Some halogenonitro‐derivatives of 1:2‐bis‐(phenylamino)‐ethane with the halogen atom in themeta‐position are first described along with their nitration to explosive nitramines. The bromination and chlorination of 1:2‐bis‐(phenylamino)‐ethane and some of its derivatives are then discussed. The nitration of the acetyl compounds of 1:2‐bis‐(phenylamino) ‐ethane and its derivatives leads to the formulation of some rules on substitution. Finally, the nitration of N.N'diphenylpiperazine and its derivatives is dealt with, the occurrence of ring opening pointing to a striking analogy with van Romburgh's nitration of dimethylaniline.Keywords
