Polymer-Supported Fe III Complex

Salicylic acid resin has also been used as a polymeric support material for FeCl3 Lewis acid [24]. This catalyst had high catalytic efficiency in ester synthesis and acetalization. 

Cationic exchange resins have been used as supports for FeCla. In esterification the catalytic activity of polymeric complexes prepared from porous type resins was much higher than that of complexes prepared from gel type resins [25].
