Procedure

A mixture of 2,2-dimethyl-3-(4-fluoro-3-phenoxybenzyloxy)propan-1-al (0.5 g), triphenylphosphine (0.43 g) and carbon tetrachloride (1.0 cm3) was heated at the reflux temperature for 1 hour. After cooling to the ambient temperature 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 redidual oil subjected to purification by flash chromatography using a silica column eluted with petroleum ether (boiling range 40°-60° C.) containing diethyl ether (10% by volume) as eluent to yield 2,2-dimethyl-1-(4-fluoro-3-phenoxybenzyloxy)-4,4-dichlorbut-3-ene (0.1 g) as a colourless oil.
