Trichloroacetyl chloride is the acyl chloride of trichloroacetic acid. It can be formed by reacting chlorine with acetyl chloride or acetaldehyde in the presence of activated charcoal, or by the isomerisation of tetrachloroethylene oxide via heating. It is used in the manufacture of pharmaceuticals and plant protection compounds. [4]
