An environmentally benign, simple and highly efficient protocol for the synthesis of S-arylisothiourea derivatives has been achieved in good to excellent yields by reacting a series of aryl iodides with arylthioureas, using inexpensive CuSO4·5H2O as catalyst in water without PTC (phase transfer catalyst). The protocol features easy performance, good to excellent yields, good tolerance towards a variety
使用廉价的CuSO 4 ·5H 2 O作为催化剂,在不使用PTC的水中,通过使一系列芳基碘化物与芳基硫脲反应,已实现了对S-芳基异硫脲衍生物进行合成的环境友好,简单且高效的方法,收率良好至优异。相转移催化剂)。该方案的特点是易于执行,良好或优异的收率,对各种官能团具有良好的耐受性,可用于制备某些生物活性化合物。
