二芳基二硫醚与锌粉在DMF 中110 ℃反应, 生成二硫醚与锌的复合物; 后者在无水AlCl3存在下与丙烯酸酯、丙烯腈反应分别生成β-芳硫基丙酸酯和相应的腈, 产率48%~91%.

关键词: 丙烯酸酯, 丙烯腈, 共轭加成, 二芳基二硫醚

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
