  Palladium-catalyzed mono- and bis(alkoxycarbonylation)s of olefins were controlled by the use of copper(II) and copper(1) chloride, respectively, in alcohol under normal pressure of carbon monoxide and oxygen at room temperature without any other additives. 3-Buten-1-ols gave the corresponding γ-butyrolactones and 2-oxotetrahydrofuran-3-acetic acid esters, respectively, in high yields.

  在室温下、正常压力的二氧化碳和氧气环境下，使用铜(II)和铜(I)氯化物分别控制钯催化的单和双(烷氧基羰基化)反应，无需其他添加剂即可使烯烃产生反应。3-丁烯-1-醇则分别高效地生成相应的γ-丁酰内酯和2-氧杂四氢呋喃-3-乙酸酯。
