CuI /反-4-羟基-1-脯氨酸催化的芳基碘化物与叔丁基β-酮酯的偶联在DMF中在40°C下顺利进行,在酸促进叔丁酯的脱保护和脱羧反应后得到α-芳基酮团体。CuI / 2-吡啶甲酸在二恶烷中于70°C催化芳基碘化物与乙酰乙酸叔丁酯偶合时,在自发脱酰作用下释放出α-芳酸叔丁酯。各种各样的官能团,例如乙酰基,甲氧基,腈,硝基,溴和氯与反应条件相容。

catalyzed coupling of aryl iodides with tert-butyl β-ketoesters proceeded smoothly at 40 °C in DMF, providing α-aryl ketones after acid-promoted deprotection and decarboxylation of tert-butyl ester group. While CuI/2-picolinic acid catalyzed coupling of aryl iodides with tert-butyl acetoacetate at 70 °C in dioxane delivered α-arylacetic acid tert-butyl esters upon spontaneous deacylation. A wide range of
