Versuchsvorschrift

4-[4-(2-benzyloxyethoxy)-phenyl]-4-(4-benzyloxyphenyl)-3-phenylbut-3-en-1-ol (1.9 g, 3.45 mmol), triphenyl phosphine (1.8 g, 6.9 mmol), carbon tetrachloride (2.6 g, 17.25 mmol) and acetonitrile (10 ml) were stirred at room temperature for an hour. The product was separated by the same method as Z-1-[4-(2-benzyloxyethoxy)-phenyl]-4-chloro-1,2-diphenyl-but-1-ene described in example 2 and purified by flash chromatography (toluene: methanol, 9.75:0.25). Yield 1.2 g.
