A direct synthesis of 13 polycyclic aromatic tellurides from the corresponding aromatic iodides has been achieved using sodium telluride, prepared by two different methods; (i) using tellurium and Rongalite HOCH2SO2Na in dilute aqueous alkali, and (ii) from tellurium and sodium hydride in dry dimethylformamide. A comparison of these two types of tellurating agents has been made.
使用通过两种不同方法制备的碲化钠,从相应的芳香族碘化物直接合成了 13 种多环芳香族碲化物; (i) 在稀碱水溶液中使用碲和雕白粉 HOCH2SO2Na,以及 (ii) 在干燥二甲基甲酰胺中使用碲和氢化钠。对这两种类型的碲化剂进行了比较。
