Oxidation of (E)-3-(4-chlorophenyl)-2-cyanoprop-2-enethioamide with hydrogen peroxide or the H2O2-KOH system gave 3-(4-chlorophenyl)oxirane-2,2-dicarboxamide. This compound was also obtained by an independent “one pot” synthesis from p-chlorobenzaldehyde and 2-cyanoacetamide through in situ oxidation of their adduct (E)-3-(4-chlorophenyl)-2-cyanoprop-2-eneamide with the H2O2-KOH system. The structure of 3-(4-chlorophenyl)oxirane-2,2-dicarboxamide was confirmed by X-ray diffraction and spectroscopic data.
