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.
