  Palladium-catalyzed Sonogashira cross-coupling of organic tellurides with alkynes

  摘要：

  Alkyl aryl tellurides and a tellurol ester were used as coupling partners in Pd(0)-catalyzed Sonogashira reactions. Microwave-assisted reactions of alkyl aryl tellurides with alkynes in the presence of Cut and catalytic amounts of Pd(PPh(3))(4) produced alkynyl arenes. Similarly, a tellurol ester on reaction with alkynes afforded alkynyl phenyl ketones in the presence of Cut and a catalytic amount of Pd(PPh(3))(4) at room temperature. (C) 2011 Elsevier Ltd.

  光刺激的碲甲基化

  摘要：

  溴代和碘代芳烃与碲酸钾在二甲基亚砜中的光刺激反应以中等收率产生了芳基甲基碲化物。该方法提供了容易获得的芳基碲化合物的途径，而这些芳基碲化合物很难用其他方法制备。

• A general procedure for the synthesis of methylthio-, methylseleno- and methyltelluro-substituted aromatic compounds
  作者：Lars Engman、Jonas S.E. Hellberg

  DOI：10.1016/0022-328x(85)80366-1

  日期：1985.12

  A one-pot procedure is described which allows the facile introduction of one or two methylchalcogeno groups into a variety of monobromo or dibromo aromatics. The bromo compounds were converted to their corresponding lithio derivatives by treatment with t-butyllithium in tetrahydrofuran at −78°C, and these derivatives were then treated, at ambient temperature with elemental sulfur, selenium, or tellurium

  描述了一种一锅法，其允许容易地将一个或两个甲基硫属元素基引入各种单溴或二溴芳族化合物中。通过在-78℃下在四氢呋喃中用叔丁基锂处理，将溴代化合物转化为其相应的硫代衍生物，然后在环境温度下用元素硫，硒或碲处理这些衍生物。最后，将所得的硫醇锂，硒酸锂和碲酸锂用甲基碘甲基化，以得到各种甲基硫属元素取代的芳族化合物的良好收率（通常为50-80％）。该方法不能用于合成邻二取代化合物或同时引入三个甲基硫属元素基。

  Sodium telluride prepared in situ from tellurium and sodium hydride in N-methyl-2-pyrrolidone was found to act as an efficient tellurating agent for nonactivated aromatic iodides, providing a simple route to a variety of diaryl tellurides, alkyl aryl tellurides and diaryl ditellurides.

  Photostimulated reaction of bromo- and iodoarenes with potassium tellurocyanate in dimethylsulfoxide produces aryl methyl tellurides in moderate yields. This method offers facile access to aryltellurium compounds which are difficult to prepare by other methods.
