A new and efficient way was developed to carry out the reaction of acetylacetone with aryl iodides under the assistance of Cu(II) and 1,1′‐trimethylene‐2,2′‐biimidazole at 100°C. 3‐Aryl‐2,4‐pentanediones were obtained in excellent yields.
开发了一种新的高效方法,可在100°C下在Cu(II)和1,1'-三亚甲基-2,2'-联咪唑的辅助下进行乙酰丙酮与芳基碘的反应。以优异的产率获得了3-芳基-2,4-戊二酮。
