A practical one-pot synthesis of azides directly from alcohols
Lalthazuala Rokhum Ghanashyam Bez
Alkyl/benzyl azides can be readily synthesized in excellent yields from their corresponding alcohols by stirring a solution of sodium azide in DMSO with a thoroughly ground equimolecular mixture of triphenylphosphine, iodine and imidazole.

A mild and highly chemoselective iodination of alcohol using polymer supported DMAP
DIPARJUN DAS JASHA MOMO H ANAL LALTHAZUALA ROKHUM
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.
