| Abstract: | The new system of Sm/ZrCl4 can be used in the cleavage of S--S bond in disulfides. The sulfur alaions are easily formed in situ from the cleavage of S--S bond in disulfides by Sm/ZrCl4 system. These living species can react with acyl chloride, aryl halides and α,β-unsaturated esters （nitriles） to afford β-thioesters, thioesters and sulfides at the room temperature, respectively. The structures of products were confirmed by IR,^1H NMR, MS spectra and elemental analysis. |
