Abstract
L'invenzione ha per oggetto un nuovo procedimento per la sintesi del 2-acetil-resorcinolo che comprende la bromurazione del 2-acetil-1,3-cicloesandione in posizione 4, con agenti bromuranti classici in solventi inerti, seguita dalla deidrobromurazione per riscaldamento in presenza di dimetilformammide.L'intermedio di reazione, il 4-bromo-1,3-cicloesandion, è rivendicato come prodotto nuovo.Questo procedimento consente di evitare l'utilizzo e lo sviluppo di gas pericolosi e di limitare la quantità di dimetilformammide impiegata.
