Wackeroxidation of terminal olefins was carried out at room temperature and atmospheric pressure by using Pd(0)/C in THF/H2O (9:1). Palladium(0)/C was proven to be highly efficientcatalyst for the Wackeroxidation of terminal olefins to the corresponding methyl ketones. The catalyst was reusable while maintaining its activity and selectivity to a high degree.
通过在THF / H 2 O(9:1)中使用Pd(0)/ C,在室温和大气压下进行末端烯烃的Wacker氧化。钯(0)/ C被证明是瓦克将末端烯烃氧化为相应的甲基酮的高效催化剂。该催化剂可重复使用,同时高度保持其活性和选择性。

Wacker oxidation of various terminal olefins with Pd-0/C-KBrO3, a nontoxic, environmentally benign, and easy to handle catalyst system, was achieved in high isolated yields. The described protocol offers an alternative to the traditional Wacker system which uses CuCl2 as co-catalyst. The catalyst is reusable while maintaining high activity and selectivity.
