Copper(II) and 2,2′-Biimidazole-promoted Novel Reaction of 4,4,4-Trifluoro-1-phenylbutane-1,3-diones with Iodobenzene Diacetate

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. A new and efficient way...
