POLYMER-SUPPORTED BASIC IONIC LIQUIDS AS AN EFFICIENT HETEROGENEOUS CATALYST FOR THE SYNTHESIS OF FLAVANONE

Flavanone were synthesized via a combination reaction between 2-hydroxy acetophenone and benzaldehyde derivatives under microwave irradiation. Reactions were carried out in the presence of polymer supported basic ionic liquid. The catalyst demonstrated to be an efficient heterogeneous catalyst for the synthesis of different kind of flavanone. The catalyst could be recycled at least four times without appreciable loss of catalytic activity.
