Sulfuration reaction of the C(sp(2))-H bond of enaminones with elemental sulfur in the presence of CuBr/K3PO4 was carried out. It provided an efficient method for the synthesis of thioethers in moderate to good yields. The protocol was also applicable to synthesize selenides when selenium powder was used instead of sulfur powder.
在CuBr/K3PO4存在下，烯胺酮的C(sp(2))-H键与单质硫发生硫化反应。该反应提供了一种以中等至良好产率合成硫醚的有效方法。当使用硒粉代替硫粉时，该方案也适用于合成硒化物。
