Studies on the selective synthetic method for dialkyl ditellurides , a representative class of organyl tellurium compounds, were presented. Considering the difficulty in conducting previous harsh reactions and in suppressing the formation of dialkyl tellurides as side products, we optimized reaction conditions for selective syntheses of sodium ditelluride and the corresponding dialkyl ditellurides . We reduced tellurium to sodium ditelluride by using NaBH and subsequently, treated the obtained sodium ditelluride with alkyl halides (RX) to give the target compounds . Consequently, by applying various alkyl halides (RX) we achieved the selective syntheses of dialkyl ditellurides (13 examples with 4 new compounds) in modest to good yields. We also suggested the mechanistic pathways to dialkyl ditellurides .
研究了二烷基二碲化物（一种有机碲化合物的典型类别）的选择性合成方法。考虑到以前进行苛刻反应和抑制作为副产物的二烷基碲化物形成的困难，我们优化了用于选择性合成碲化钠和相应的二烷基二碲化物的反应条件。我们使用 NaBH 将碲还原为碲化钠，然后用烷基卤化物（RX）处理得到的碲化钠以得到目标化合物。因此，通过使用各种烷基卤化物（RX），我们以中等至良好的收率实现了二烷基二碲化物（13 个实例中有 4 个新化合物）的选择性合成。我们还提出了二烷基二碲化物的可能的反应途径。
