据报道,在富电子的2,6-二烷氧基苯甲酸衍生物和二芳基二硫化物之间进行脱羧钯催化反应,可轻松制得二芳基硫化物。在Pd(CF 3 CO 2)2和Ag 2 CO 3在1,4-二恶烷和四亚甲基亚砜(TMSO)的65:1混合物中存在时,该偶联有效地进行。我们还介绍了通过钯催化的脱羧交叉偶联的碳-硒键的首次形成。

The newly prepared complex [Pd(IPr*OMe)(cin)(Cl)] provides high catalytic activity for carbon–sulfur cross-coupling reactions. Nonactivated and deactivated aryl halides were successfully coupled with a large variety of aryl- and alkylthiols using this well-defined palladium N-heterocycliccarbene (NHC) complex.
