Reactions and uses
Hexachloroacetone functions equivalently to trichloroacetyl chloride, i.e. as an trichloroacetylating agent.[1]
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:[2]
- (CCl3)2CO + 6 HF → (CF3)2CO + 6 HCl
