Oxidation of (E)-3-aryl-2-cyanoprop-2-enethioamides with 32% H 2O2 under mild conditions gave (E)-3-aryl-2-cyano-1- iminioprop-2-ene-1-sulfenates in 70-88% yields. Under the conditions of the Radziszewski reaction (H2O2, 10% aqueous KOH) or upon prolonged treatment with H2O2, (E)-3-aryl-2-cyanoprop-2- enethioamides underwent transformations leading to complex mixtures of oxidation products. In some cases, 3-aryloxirane-2,2-dicarboxamides were isolated from those mixtures in low yields (<20%). Treatment of 3-arylamino-2-cyanoprop-2- enethioamides with the system H2O2/KOH in ethanol afforded (arylaminomethylidene)malononitriles. © 2012 Springer Science+Business Media New York. Source
