A new “carbon monoxide‐free” synthesis of carboxylate derivatives via carbonylative coupling of aryl bromides with phenols, alcohols, amines and acids in the presence of copper(I) bromide as catalyst and sodium cyanide in a stoichiometric amount has been developed. Its intramolecular version provides for the preparation of lactones (e.g., isochroman‐1‐ones and isobenzfuranones), imides, anhydrides
已经开发出一种新的“无一氧化碳”羧酸酯衍生物的合成方法,该方法是在溴化铜(I)和化学计量的氰化钠存在下,通过芳基溴化物与苯酚,醇,胺和酸的羰基化偶联进行的。其分子内版本可制备内酯(例如,异色满-1-酮和异苯并呋喃酮),酰亚胺,酸酐和内酰胺,收率极高(73-96%)。
