Method of making coupled 4,6-dibenzoylresorcinols |
| abstract |
An improved method of making methylene-bridgedn4,6-dibenzoylresorcinol dimers in a singlenstep in high yield quantities is provided. The methodnheats a 4,6-dibenzoylresorcinol (DBR) with a para-aldehydenor an aromatic aldehyde in a carboxylic acidnsolvent in the presence of a strong acid catalyst. |
