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.
