Isopropyl iodide is the organoiodine compound with the formula (CH3)2CHI. It is colorless, flammable, and volatile. Organic iodides are light-sensitive and take on a yellow colour upon storage, owing to the formation of iodine.

Preparation

[edit]

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 sodium iodide (Finkelstein reaction):[3]

(CH3)2CHBr + NaI → (CH3)2CHI + NaBr
