Diaryldisulfides reacted with zinc power at 110 ℃ in DMF to give zinc-disulfide complexes which then underwent conjugate addition to acrylic esters or acrylnitrile at 70 ℃ in the presence of anhydrous AlCl3 to afford β-arylthio propanoic esters and corresponding nitriles in 48%~91% yields, respectively.

Key words: acrylnitrile, diaryldisulfide, conjugate addition, acrylic ester
