The Fries rearrangement of 3-chlorophenyl acetate provided the expected 4-chloro-2-hydroxy-acetophenone as the major product and 2,4-diacetyl resorcinol and 2-chloro-4-hydroxy-acetophenone as minor products. 4-Benzyloxy-2-chloroacetophenone was prepared by a Heck reaction and then elaborated to 4-benzyloxy-2-chlorophenacyl azide.

由4-溴-3-氯苯酚对Fries重排3-氯乙酸苯酯的重新研究和2-叠氮基-1-（4-（苄氧基）-2-氯苯基）乙酮的合成

3-氯苯基乙酸的弗里斯重排提供了预期的4-氯-2-羟基-苯乙酮为主要产物，而2,4-二乙酰基间苯二酚和2-氯-4-羟基-苯乙酮为次要产物。通过Heck反应制备4-苄氧基-2-氯苯乙酮，然后将其精制为4-苄氧基-2-氯苯甲酰基叠氮化物。
