    • To remove a trace amount of sulfonic acid, para-toluenesulfonyl chloride was recrystalized from hexanes prior to use.

    • Typical reaction procedure: To a solution of para-toluenesulfonyl chloride (190 mg, 1.0 mmol) in tetrahydrofuran (5 mL) was added triphenylphosphine (524 mg, 2.0 mmol). The mixture was stirred at room temperature and monitored by TLC. After completion of the reaction, the solvent was removed under reduced pressure and the residue was dissolved in a minimum amount of ethyl acetate (4 mL). To this solution, hexane was added dropwise (about 30 mL) and the byproduct triphenylphosphine oxide was precipitated and was removed by filtration. Concentration of the filtrate under reduced pressure and silica gel column chromatography using hexane as eluant yielded the desired product (114 mg, 92% yield).

    • The light yellow color of the reaction mixtures suggests that chlorine may be a byproduct. However, attempts to detect chlorine using wet KI-Starch paper were unsuccessful.
