摘要：

The mixture of cesium hydroxide and terminal alkynes in dry DMF in the presence of 4 angstrom molecular sieves was stirred for 3.0 h at room temperature under N-2, then aryltellurenyl bromide in THF was added, and the reaction mixture was stirred for 2.0 h. Alkynyl tellurides were obtained in about 90% yields by flash chromatography. (c) 2008 Xin Hua Xu. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
