Pd–C can catalyze the carbonylation of terminal olefins with normal pressure of carbon monoxide at room temperature. The corresponding mono- and diesters (succinates) were selectively formed in excellent yields using Cu(II) and Cu(I) chloride, respectively, in alcohol.
Pd-C可以在常压下在一氧化碳常压下催化末端烯烃的羰基化反应。分别使用氯化铜 (II) 和氯化铜 (I) 在醇中选择性地形成相应的单酯和二酯(琥珀酸酯),收率极好。

A porous solidcatalyst component comprising a magnesium halide, a titanium compound having at least a Ti-halogen bond and at least two electron donor compounds one of which being selected from 1,3-diethers and the other being selected from succinates, characterized by the fact that the molar ratio ID/Ti is from 0.30 to 0.90, where ID is the total molar amount of succinate and 1,3-diether, the molar ratio of the 1,3-diether donor tothe succinate donor is higher than, or equal to, 0.60.
Selective Mono- and Bis(alkoxycarbonylation)s of Olefins Catalyzed by Palladium in the Presence of Cu(I) or Cu(II) Chloride under Remarkably Mild Conditions. Application to the Synthesis of γ-Butyrolactone Derivatives
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.
