Application of multipurpose dimethyl formamide-like task specific ionic liquid as a recyclable reagent for direct iodination of alcohols

A direct and an efficient conversion of a wide range of primary, secondary even tertiary alcohols to the corresponding iodides have been achieved under ionic liquid conditions. The method involves preparation of ionic liquid-based iminium chloride intermediate from DMF-like ionic liquid then stirring it with alcohol in present of sodium iodide. The higher yields of alkyl iodides were obtained within minimum time with simplest operational procedure. The DMF-like ionic liquids could be recycled.
