Hexachloroacetone is an organic compound with the formula (Cl₃C)₂CO. It is also called hexachloropropanone or perchloroacetone. Numbers indicating the position of the chlorine-atoms are generally omitted as all the possible positions are substituted with chlorine. It is a colorless liquid, slightly soluble in water.

Reactions and uses

Hexachloroacetone functions equivalently to trichloroacetyl chloride, i.e. as an trichloroacetylating agent.^[2]

The main use of hexachloroacetone is as a pesticide. For the use of hexachloroacetone in the preparation of a novel insect repellent see Perkow reaction. The industrial route to hexafluoroacetone involves treatment of hexachloroacetone with HF:^[3]

(CCl₃)₂CO + 6 HF → (CF₃)₂CO + 6 HCl
