| | Copper (I) phenylacetylide Usage And Synthesis |
| Uses | Copper(I) phenylacetylide participates in efficient coupling with a range of aryl iodides and bromides to give substituted tolaneswhich, if possessing anorthoamino or hydroxy group, can be thermolyzed to yield 2-phenylbenzofurans, -indoles, and -furo[3,2-b]pyridines. | | Application | Copper (i) phenylacetylide is a mild nucleophile used to introduce phenylethynyl groups to form phenylpropene and Glazer cross-coupling products. | | Preparation | (i) Phenylacetylene is treated with either ammoniacal Copper(II) Sulfate and Hydroxylamine hydrochloride (reductant) or Copper(I) Iodide in ethanol; (ii) phenylacetylene is lithiated, then treated with copper(I) iodide; (iii) phenylacetylene is treated with Copper(I) t-Butoxide.
Drying: heat (65 °C) under vacuum. | | storage | All copper(I) acetylides are potentially explosive in the solid state. Use in a fume hood. |
