A new and efficient way was developed to carry out the reaction of 4,4,4‐trifluoro‐1‐phenylbutane‐1,3‐dione with iodobenzene diacetate under the assistance of Cu(II) and 2,2′‐biimidazole at a low temperature in excellent yield. 2‐Acetoxyacetophenone was obtained unexpectedly.
在Cu(II)和2,2'-联咪唑的协助下,开发了一种新的高效方法来进行4,4,4-三氟-1-苯基丁烷-1,3-二酮与碘代苯二乙酸的反应。低温,产率高。意外地获得了2-乙酰氧基苯乙酮。
