Procedure

A solution of 4-methyl-3-(trichlorovinyl)benzyl alcohol (2.06 g) and triphenylphosphine (2.58 g) in 100 ml of carbon tetrachloride was heated at reflux for 48 hours. The reaction mixture was concentrated under reduced pressure and the residue dissolved in CH2Cl2 (200 ml). This organic solution was shaken with 30% H2O2 (10 ml) and then diluted with water (100 ml) and the layers separated. The organic layer was further washed with water, dried with anhydrous magnesium sulfate and concentrated to give 4.37 g of crude product. Chromatography on silica (1:1 hexane:methylene chloride) gave 1.81 g of 4-methyl-(trichlorovinyl)benzyl chloride.
