  由K 3 PO 4和DMSO介导的炔基碲化物的合成†

  摘要：

  在目前的工作中，描述了一种简单的合成炔基碲化物的方法，该方法是在催化量的K 3 PO 4存在下，末端炔烃与二有机基二碲化物反应。在两种底物中，都可以改变芳基和烷基，从而以较短的反应时间和30％至93％的产率获得目标产物。该方法与文献中已经报道的方法不同，具有使用催化量的弱碱而不使用金属催化剂的优点。

• A General and Highly Efficient Protocol for the Synthesis of Chalcogeno­acetylenes by Copper(I)-Terpyridine Catalyst
  作者：Barahman Movassagh、Badri Momeni、Ali Yousefi、Sepideh Heydari

  DOI：10.1055/s-0033-1341277

  日期：——

  A highly efficient copper-catalyzed C-sp-X (X = S, Se, Te) bond-forming reaction of terminal alkynes and diorganyl dichalcogenides has been developed. This transformation was realized through the use of copper(I) iodide as a catalyst, 4'-(4-methoxyphenyl)-2,2':6',2 ''-terpyridine as a ligand, and K3PO4 as a base. A variety of the functionalized substrates were found to react under these reaction conditions to provide products in good to excellent yields.

  We present herein a new and efficient methodology for the synthesis of alkynyl chalcogenides from terminal acetylenes and diorganyl dichalcogenides, catalyzed by Fe3O4 nanoparticles. This new approach provided the desired products in good to excellent yields. Moreover, the catalyst was easily recoverable using an external magnet and reused for further experiments without loss of catalytic activity. (C) 2013 Elsevier Ltd. All rights reserved.

  In the presence of a catalytic amount of cesium hydroxide under an air atmosphere, the reaction of diarylditellurides (1.0mmol) with terminal alkynes (2.2mmol) at room temperature exclusively give alkynyl tellurides in good yields.
