Unsaturated compounds containing keto groups bound to rings other than six-membered aromatic rings

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Ketones; Ketenes; Dimeric ketenes; Ketonic chelates > Unsaturated compounds containing keto groups bound to rings other than six-membered aromatic rings

CPC:

Ketones; Ketenes; Dimeric ketenes (heterocyclic compounds C07D, e.g. beta-lactones C07D305/12); Ketonic chelates > Unsaturated compounds containing keto groups bound to rings other than six-membered aromatic rings

IPC and CPC are identically structured here. All 11 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
