Hydrothiolation of 1-organylbuta-1,3-diynes and 1,4-diorganylbuta-1,3-diynes with the sodium organylthiolate anions, which were generated in situ by reacting diphenyl and dibutyl disulfide with NaBH4 in ethanol, results in the regio-, stereo-, and chemoselective formation of (Z)-1-organylthio-4-organylbut-1-en-3-ynes and (Z)-1-organylthio-1,4-diorganylbut-1-en-3-ynes, respectively.
1-organylbuta-1,3-diynes 和 1,4-diorganylbuta-1,3-diynes 与organylthiolate 钠阴离子发生氢硫化反应、分别生成了 (Z)-1-organylthio-4-organylbut-1-en-3-ynes 和 (Z)-1-organylthio-1,4-diorganylbut-1-en-3-ynes。
