    摘要: The present invention concerns novel nitrogen-containing aromatic heterocyclic compounds of the formula: ##STR1## wherein R is a group of the formula ##STR2## wherein R.sub.1 and R.sub.2 are substituents, e.g. alkyl and R.sub.3 is hydrogen or a substituent, e.g. alkyl; R.sub.4 is a group R.sub.14 --X--, wherein R.sub.14 is a substituent, e.g. alkyl and X is --O--, --S-- or ##STR3## wherein R.sub.6 is hydrogen or a substituent, e.g. alkyl, or R.sub.4 is a heterocyclic ring or has one of the significances of R; R.sub.5 has one of the significances of R.sub.4 ; and Y is --N.dbd. or --CH.dbd..The compounds are useful as anti-oxidants in, e.g. plastics materials.
