実験手順

A mixture of 1-chloro-3-(triphenylphosphanylidene)-propane-2-one (2.8 g, 7.9 mmol) and freshly distilled benzaldehyde (0.7 g, 6.6 mmol) in toluene (10 ml) is heated at reflux for 20 hours. Evaporation to dryness yields a mixture containing the title compound that is used in the subsequent step without purification.
