Hexachloroacetone is an

organic compound Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-co ...

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. The main use of hexachloroacetone is as a pesticide. For the use of hexachloroacetone in the preparation of a novel
