ABSTRACT

A new facile methodology for the synthesis of aromatic thioureas by desulphurization and addition reaction of the required amine, carbon disulfide and ammonia solution in the presence of DMSO solvent using iron at room temperature. The structures of the synthesized compounds were confirmed by IR, and, 1H-NMR methods The synthetic benefits of the presented methods are reflected in the operational simplicity, mild reaction conditions, short reaction times, high purity and yield of the products. Considering the commercial importance of thioureas, it should be emphasized that implementation of the optimal synthesis of thiourea determined good intermediate for the synthesis heterocyclic compounds having good biological activity from amines using iodine as a reagent.

Keywords: Amine, carbon disulfide and ammonia.
