Page/Page column 52-53, (2013/02/28)
The present invention relates to substituted heteroaromatic dianlamine compounds of Formula I and II, their pharmaceutically acceptable salts, and compositions thereof useful as antioxidants, wherein each of X, Y and Z are independently a carbon or nitrogen atom; R1 and R2 are each independently a hydrogen or an electron donating group, but are not both hydrogen, and wherein R1 and R2 are each bonded to a carbon atom in their own respective aryl ring.

The incorporation of nitrogen atoms into the aryl rings of conventional diphenylamine antioxidants enables the preparation of readily accessible, air-stable analogues, several of which have temperature-independent radical-trapping activities up to 200-fold greater than those of typical commercial diphenylamines. Amazingly, the nitrogen atoms raise the oxidation potentials of the amines without greatly changing their radical-trapping (H-atom transfer) reactivity.
