To potassium t-butoxide (5.6 g, 50 mmol) in DMF (40 mL) at 75° C. was added N-(phenylmethyl)-1H-1,2,4-triazole (1.59 g, 10 mmol) and N-(phenylmethylene)benzenamine (1.81 g, 10 mmol) dissolved in DMF (10 mL). After 30 minutes the solution is poured into ice-cold water (150 mL), extracted with CHCl3 (3×50 mL) and chromatographed (PE). Diphenylacetylene was obtained in 11% yield.
