Incorporation of ring nitrogens into diphenylamine antioxidants: Striking a balance between reactivity and stability

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.

SUBSTITUTED DIARYLAMINES AND USE OF SAME AS ANTIOXIDANTS

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.

Diphenylamino and indolyl substituted pyromellitides

This invention relates to 3,7-bis(disubstituted aminophenyl- or indolyl)-3,7-bis(diphenylamino)pyromellitides, 3,5-bis(disubstituted aminophenyl- or indolyl)-3,5-bis(diphenylamino)pyromellitides and mixtures thereof useful as color formers, particularly in carbonless duplicating and thermal marking systems, which are prepared by the interaction of 2,5-bis(disubstituted aminophenyl- or indolyl)carbonyl-1,4-benzenedicarboxylic acids or 2,4-bis(disubstituted aminophenyl- or indolyl)carbonyl-1,5-benzenedicarboxylic acids and mixtures thereof with diphenylamines.
