  日期：2015.2.2

  A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a broad range of thiols with high chemioselectivity. The complete conversion of disulfides to thiocyanates was also possible. Preliminary computational

  描述了一种使用氰基苯并齐多醇（on）高价碘试剂氰化硫醇和二硫化物的新方法。脂肪族和芳香族硫氰酸酯都可以在室温下以几分钟的高收率获得，其起始源是多种具有高化学选择性的硫醇。也可以将二硫化物完全转化为硫氰酸酯。初步的计算研究表明，硫氰酸根阴离子或自由基的氰化反应具有低能的一致过渡态。发达的硫氰酸酯合成方法在合成化学，化学生物学和材料科学中具有广泛的应用潜力。
