To obtain detoxicated derivatives of α-halogenoketones, enol acetates have been prepared from ten α-aryl-α-halogenoacetophenones by reaction of the sodium enolates with acetyl chloride; the conventional method using isopropenyl acetate was completely ineffective. Simple α-halogenoacetophenones are resistant to both procedures, and the conjugative influence of an α-aryl substituent on the stability
