SUMMARY
The halogenation of alcohols, specifically the conversion of ROH to RI, can be effectively achieved using the Finkelstein reaction. The process involves the initial conversion of ROH to RBr using phosphorus tribromide (PBr3), followed by the substitution of bromine with iodine through sodium iodide (NaI). While direct iodination using phosphorus triiodide (PI3) or hydroiodic acid (HI) is possible, the Finkelstein method is often preferred due to cost considerations and reaction efficiency.
