Synthesis of Polynitrodiazophenols

Atkins, Ronald L.,Wilson, William S.

, p. 2572 - 2578 (2007/10/02)

The formation of diazophenols by nitration of suitably substituted anilines and rearrangement of the nitroaromatic nitramines so formed is presented.The scope of the reaction is discussed, and a mechanism for the nitramine/diazophenol rearrangement is proposed which is consistent with 15N-labeling experiments.
