Reaction of 3-aryl-2-cyanoprop-2-enethioamides with bromonitromethane: a new method for the synthesis of functionalized 1,2,4-thiadiazoles

Reaction of 3-aryl-2-cyanoprop-2-enethioamides with bromonitromethane: a new method for the synthesis of functionalized 1,2,4-thiadiazoles

The reaction of 3-aryl-2-cyanoprop-2-enethioamides with bromonitromethane leads to the products of oxidative dimerization, (2E,2'E)-2,2'-(1,2,4-thiadiazole-3,5-diyl)bis(3-arylacrylonitriles). Their structure was confirmed by the counter synthesis through the oxidation of 3-aryl-2-cyanoprop...

Zusammenfassung:The reaction of 3-aryl-2-cyanoprop-2-enethioamides with bromonitromethane leads to the products of oxidative dimerization, (2E,2'E)-2,2'-(1,2,4-thiadiazole-3,5-diyl)bis(3-arylacrylonitriles). Their structure was confirmed by the counter synthesis through the oxidation of 3-aryl-2-cyanoprop-2-enethioamides by DMSO-HCl system. Keywords: bromonitromethane, 2-cyanoprop-2-enethioamides, cyanothioacetamide, dimethyl sulfoxide, 1,2,4-thiadiazoles, oxidative dimerization.
