ABSTRACT
N,N-Diaryl-N′,N′-1,4-phenylenedi(oxyacetyl)-dithioureas (3a–l) are synthesized under solid–liquid phase transfer catalysis. Meanwhile, the corresponding diureas of 3a–l, N,N-Diaryl-N′,N′-1,4-phenylenedi(oxyacetyl)-diureas (4a–l), are further synthesized by the reaction of 3a–l with potassium iodate in high yield.
