Tricyclo Ring System Which Contains The Hetero Ring As One Of The Cyclos Patents (Class 540/586)
- The nitrogen of the hetero ring is bonded directly to each of the two benzene rings (e.g., iminodibenzyl, etc.) (Class 540/588)
- Having -C(=X)-, wherein X is chalcogen, bonded directly to ring nitrogen of the tricyclo ring system (Class 540/589)
- Nitrogen attached directly or indirectly to ring carbon of the hetero ring by acyclic nonionic bonding (Class 540/590)
- Chalcogen attached directly or indirectly to the hetero ring by acyclic nonionic bonding (Class 540/591)
- Nitrogen attached indirectly to ring nitrogen of the hetero ring by acyclic nonionic bonding (Class 540/592)
