meta quinone methide[edit]
how would a meta quinone methide be possible? this article says that quinone methides are substituted cyclohexadienes with a carbonyl and an exocyclic methylene group. there is no way a cyclohexadiene ring can have an exocyclic methylene and a carbonyl group in meta positions, it would have a pentavalent and a trivalent carbon atom! — Preceding unsigned comment added by 80.147.106.67 (talk) 10:19, 29 January 2014 (UTC)
- It does exist but can't been draw as a Kekule structure, you have to depict it as a di-radical. --Project Osprey (talk) 11:21, 14 February 2020 (UTC)
