Copper(II) and 1,1′-Trimethylene-2,2′-biimidazole-promoted Arylation of Acetylacetone with Aryl Iodides

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. A new and efficient way was developed to carry out the reacti...
