tropolone
Tropolone is an organic compound with the formula C7H6O2. It consists of a seven-membered ring that bears a ketone carbonyl and an adjacent hydroxyl group, is named systematically as 2-hydroxycyclohepta-2,4,6-trien-1-one. The ring contains a conjugated system and is regarded as a non-benzenoid aromatic compound, reflecting significant delocalization of π electrons despite its unusual ring size.
The molecule features a hydroxy-ketone arrangement that allows tautomeric and resonant stabilization within a cyclic conjugated
Tropolone was named after Tropaeolum, the genus of nasturtium, from which the compound was historically first
Synthesis of tropolone typically involves constructing the seven-membered ring with the appropriate hydroxy and carbonyl functionalities,
