Class Information
Number: 548/549
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Chalcogen attached directly to the five-membered hetero ring by nonionic bonding (e.g., 3-pyrrolidinols, etc.) > Chalcogen bonded directly to a ring carbon of the five-membered hetero ring which is adjacent to the ring nitrogen (e.g., 2-pyrrolidones, etc.) > And chalcogen bonded directly to the other ring carbon of the five-membered hetero ring which is adjacent to the ring nitrogen (e.g., succinimide, etc.) > Carbon to carbon unsaturation between ring members of the five-membered hetero ring (e.g., maleimide, etc.) > Benzene ring bonded directly to ring nitrogen of the five-membered hetero ring (e.g., n-phenylmaleimide, etc.)
Description: Compounds wherein a benzene ring is bonded directly to ring nitrogen of the five-membered hetero ring.
