Isopropyl iodide is prepared by iodination of isopropyl alcohol using hydrogen iodide or, equivalently, with a mixture of glycerol, iodine, and phosphorus.[2] An alternative preparation involves the reaction of 2-propyl bromide with an acetone solution of potassium iodide (KI):[3]

(CH3)2CHBr + KI → (CH3)2CHI + KBr
