DEFINITION

Classification: 546/248

Chalcogen attached indirectly to the piperidine ring by nonionic bonding:

(under subclass 184) Compounds in which chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is attached indirectly to the piperidine ring by nonionic bonding. [figure] [caption]Aliphatic

(1) Note. A compound of the type would be provided for herein rather than above in subclasses 242+ as the chalcogen which is bonded directly to the six-membered hetero ring is attached to the ring nitrogen rather than a ring carbon. Placement is based on the oxygen which is attached indirectly, i.e., through a sulfur atom, to the six-membered hetero ring.

(2) Note. Additional examples of compounds provided for herein are: [figure] [figure]
