Copper-catalyzed domino intra- and intermolecular C-S cross-coupling reactions: synthesis of 2-(arylthio)arylcyanamides.
One-pot synthesis of 2-(arylthio)arylcyanamides is accomplished using cheap and air-stable CuSO(4) x 5 H(2)O as a catalyst by domino intra- and intermolecular C-S cross-coupling reactions of 2-(iodoaryl)thioureas with aryl iodides under ligand-free conditions.
