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 aryliodides 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
A convenient and efficient protocol has been developed for the preparation of aryl-isothioureas based on the Chan-Lam C-S couplingreaction. The desired aryl-isothioureas were synthesized in good yields (up to 95%) in the presence of Cu(OAc)(2)H2O as catalyst and bipyridine as ligand. A variety of functional groups on the aryl-thiourea and arylboronic acid reagents are tolerated. The method features
