二苯基二硫化物与硝基甲烷在2当量碘单质和5当量乙酸钾作用下,生成相应的硫氰酸酯,13例收率51%~92%。苯环对位有羟基或硝基取代会显著降低收率,卤素取代在邻位、间位或对位,收率相似。杂环化合物如二噻吩二硫化物或二吡啶二硫化物收率分别为60%和51%。非芳香二硫化物及二硒化物也能发生反应,3例收率40%~78%。 Diphenyl disulfide and nitromethane in 2 equivalents of iodine and 5 equivalents of potassium acetate to generate the corresponding thiocyanate, 13 cases yield 51% to 92%. Substitution of the para-position of the phenyl ring with a hydroxyl group or a nitro group can significantly reduce the yield. The halogens are substituted in the ortho, meta or para position with similar yields. The yield of heterocyclic compounds such as dithiophene disulfide or dipyridyl disulfide was 60% and 51%, respectively. Non-aromatic disulfides and diselenide can also react, 3 cases yield 40% to 78%.
