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
为了获得α-卤代酮的脱毒衍生物,通过烯醇酸钠与乙酰氯的反应,由十种α-芳基-α-卤代乙酰苯制备了烯醇乙酸酯。使用乙酸异丙烯酯的常规方法是完全无效的。简单的α-卤代乙酰苯对这两种方法均具有抗性,因此证明了α-芳基取代基对烯醇根阴离子稳定性的共轭影响。记录烯醇乙酸酯的紫外线和红外吸收最大值。
