The mixture of cesium hydroxide and terminal alkynes in dry DMF in the presence of 4(Å), molecular sieves was stirred for 3.0 h at room temperature under N₂, 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.
- Cesium hydroxide,
- Terminal alkynes,
- Alkynyl teiluiride
