A mild and highly chemoselective iodination of alcohol using polymer supported DMAP

The synthesis of organic compounds using polymer supported catalysts and reagents, where the required product is always in solution, has been of great interest in recent years, both in industries and academia especially in pharmaceutical research. Here, a simple and efficient method for conversion of alcohols into their iodides in high yield using polymer supported 4-(Dimethylamino)pyridine (DMAP) is described. Polymer supported DMAP is used in catalytic amount and is recovered and reused several times. Additionally, this method is highly chemoselective. Graphical Abstract A mild and highly selective iodination of alcohols using polymer supported 4-(Dimethylamino)pyridine (DMAP) in catalytic amount is reported. The base catalyst can be easily recovered by simple filtration and reused several times without appreciable loss in activity.
