Reaction Conditions

Reaction Steps

A mixture of 1,4-bis(allyloxy)-2-butyne (157 mg, 1.02 mmol) and (p-cymene)RuCl(PCy3)(═C═C═CPh2)+PF6− (22 mg) in toluene (5 mL) is stirred for 3 h under argon at 80° C. The solvent is evaporated and the residue purified by flash chromatography using diethylether/pentane (1/4) as eluent. This affords the title compound as white solid (110 mg, 86%). 1H NMR (200 MHz, CDCl3): δ=4.70 (br. S, 8H), 5.59 (s, 2H). 13C NMR (50 MHz, CDCl3): δ=74.7, 76.0, 122.5, 131.4.
