REACTIVITY OF AMIDINES OF THE ANTHRAQUINONE SERIES.

Shapkin, V. P.,Popov, S. I.

, p. 153 - 159 (2007/10/02)

The introduction of an amidine group into 1-arylamino- and α,α'-diarylaminoanthraquinones fully deactivates the aryl ring attached to the amidine group toward bromination in acetic acid but partly passivates the ring in sulfuric acid solutions.This makes it possible to introduce bromine at the meta position to the amidine group with the para position occupied and subsequently to introduce bromine into the various aryl rings.
