Versuchsvorschrift
5 g (26 mmol) of 2-trifluoromethoxybenzyl bromide and 8.5 g (24.7 mmol) of triphenylphosphonium bromide are stirred under reflux in 100 ml of acetonitrile for 3 h. After cooling, the resulting precipitate is filtered off with suction and dried. 13.5 g (26 mmol, 100% of theory) of the title compound are obtained.
