Reaktionsschritte
8.5 g of p-bromophenyl-sulfur pentafluoride and 20 ml of piperidine are added to a mixture of 8.5 g of 4-pentoxyphenylacetylene, 20 ml of piperidine, 420 mg of triphenylphosphine-palladium(II) chloride and 30 mg of copper iodide, and the combined mixture is heated for 20 hours. Concentration and working up in the customary manner gives 4-(2-(4-pentoxyphenyl)-ethynyl)-phenyl-sulfur pentafluoride.
