'''Hexachloroacetone''' is an organic compound with the formula (Cl<sub>3</sub>C)<sub>2</sub>CO. 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.<ref>{{cite journal |doi=10.15227/orgsyn.040.0103|author=Bernard Sukornick|title=α,α,α-Trichloroacetanilide|journal=Organic Syntheses|year=1960|volume=40|page=103}}</ref>

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:<ref name=Ullmanns>{{cite encyclopedia|author=Günter Siegemund |author2=Werner Schwertfeger |author3=Andrew Feiring |author4=Bruce Smart |author5=Fred Behr |author6=Herward Vogel |author7=Blaine McKusick |encyclopedia=Ullmann's Encyclopedia of Industrial Chemistry|publisher=Wiley-VCH|place=Weinheim|year=2002|doi=10.1002/14356007.a11_349|chapter=Fluorine Compounds, Organic|isbn=3-527-30673-0}}</ref> :(CCl<sub>3</sub>)<sub>2</sub>CO + 6 HF → (CF<sub>3</sub>)<sub>2</sub>CO + 6 HCl
