| Abstract: | A highly efficient method for the synthesis of 1,4-phenylenedithioureas promoted by microwave irridiation is reported. It is based on the nucleophilic addition reaction of 1,4-phenylenediisothiocyanate to aromatic amines under solvent- and catalyst-free conditions. The reaction has the advantages of short reaction time, good yields, and environmental acceptability. |
