The Reaction of Aromatic Aldehydes and 1,3‐Cyclohexanedione in Aqueous Media

Abstract

The reaction of aromatic aldehyde and 1,3‐cyclohexanedione in aqueous media has been catalyzed by p ‐dodecylbenezenesulfonic acid (DBSA) or sodium dodecyl sulfate (SDS) and yields two products: 9‐aryl‐1, 8‐dioxooctahydroxanthene derivatives and 2,2´‐arylmethylene bis (3‐hydroxy‐ 2‐cyclohexene‐1‐one). This method provides several advantages such as good yield, simple work‐up procedure and environment friendly.
