 Iodoacetone

Iodoacetone is the alpha-iodinated ketone $\mathrm{C}{\mathrm{H}}_3\mathrm{COC}{\mathrm{H}}_2\mathrm{I}$. It combines a carbonyl group with an adjacent carbon bearing a leaving group.

The molecule can therefore participate in chemistry at either functional site. Its identity is more specific than a mixture of acetone and an iodide salt: the iodine is covalently attached to the carbon framework.
