実験手順

A mixture of 2,2-dimethyl-3-(3-phenoxybenzyloxy)propan-1-al (0.25 g), triphenylphosphine (0.47 g), zinc dust (0.12 g) and carbon tetrachloride (0.2 cm3) was heated at the relux temperature for one hour. After cooling to the ambient temperature (ca 25° C.) the mixture was diluted with petroleum ether (boiling range 40°-60° C.) and the solid component removed by filtration. The filtrate was concentrated by evaporation of the solvent under reduced pressure, and the residual oil subjected to purification by flash chromatography using a silica gel column eluted with dichloromethane to yield 2,2-dimethyl-1-(3-phenoxybenzyloxy)-4,4-dichlorobut-3-ene (0.2 g).
