2-chloroethynylbenzene

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Phenylacetylene (1.02 g, 10 mmol), 1.92 g of cesium carbonate (10 mmol), and 0.15 g tetra-n-butylammonium chloride hydrate and 5 mL carbon tetrachloride were mixed at 70° C. for 5 h. Gas chromatographic analysis of the mixture showed that it contained 1.32 g of 1-chloro-2-phenylacetylene (96% yield).

Conditions: temp:24.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a 10 mL round-bottom flask, a mixture of 0.51 g phenylacetylene (5 mmol), 0.7 g potassium carbonate (5 mmol), 165 mg tetra-n-butylammonium fluoride trihydrate, and 3 mL tetrachloromethane was stirred at 24° C. for 10 min. After filtration of the solids, the filtrate was found to contain 0.68 g of 1-chloro-2-phenylacetylene (99% yield). After filtration of the solids
