anilines were efficiently transformed into isothiocyanates (in presence of 5.0 equiv. CS2) or symmetrical thioureas (in presence of 1.0 equiv. CS2), without using any other harsh or toxic decomposition reagent. Some in situ generated isothiocyanates can directly “click” with other amines to afford unsymmetrical thioureas.
推动者 酸值在球磨下,无需使用任何其他刺激性或有毒的分解试剂,即可将苯胺有效地转化为异硫氰酸酯(存在5.0当量CS 2)或对称硫脲(存在1.0当量CS 2)。一些原位生成的异硫氰酸酯可以直接与其他胺“点击”,从而提供不对称的硫脲。
