The preparation of imides via the palladium-catalyzed coupling reaction as a one-carbon elongation reaction is described. The palladium-catalyzed coupling reaction of aryl-, alkyl-, and alkenylborons with N-[methoxy(methylthio)methylene]carbamate in the presence of Cu(I) thiophene-2-carboxylate (CuTC) affords imino ethers that are converted to the corresponding imides by acidic hydrolysis in high yield
描述了通过钯催化的偶联反应作为一碳延伸反应制备酰亚胺。在噻吩-2-羧酸铜(I)存在下,芳基-,烷基-和烯基硼与N- [甲氧基(甲硫基甲基)亚甲基]氨基甲酸酯的钯催化偶联反应提供亚氨基醚,该亚氨基醚被转化为酸水解得到相应的酰亚胺,产率很高。亚氨基醚也可用于制备相应的酯而不使用一氧化碳。
