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。

using a decarboxylativepalladium-catalyzed reaction between electron-rich 2,6-dialkoxybenzoic acid derivatives and diaryl disulfides is reported. This coupling proceeds efficiently in the presence of Pd(CF3CO2)2 and Ag2CO3 in a 65:1 mixture of 1,4-dioxane and tetramethylene sulfoxide (TMSO). We present also the first formation of a carbon–selenium bond via a palladium-catalyzeddecarboxylative cross-coupling
