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 a 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
