Abstract In the presence of a catalytic amount of cesium hydroxide under a nitrogen atmosphere, terminal alkynes reacted with diaryl disulfides at room temperature in dimethylformamide to give almost exclusively (Z)-1,2-diarylthio-1-alkene in good yields, but under an air atmosphere, the reaction gave a mixture of alkynyl sulfide and (Z)-1,2-diarylthio-1-alkene.
摘要 在氮气氛下,在催化量的氢氧化铯存在下,末端炔烃在室温下在二甲基甲酰胺中与二芳基二硫化物反应,以良好的产率几乎完全得到 (Z)-1,2-二芳硫基-1-烯烃,但在在空气气氛下,反应得到炔硫醚和(Z)-1,2-二芳硫基-1-烯烃的混合物。
