Abstract

Pyrolysis of 2-(N-phenyl carboxamidomethylthio) 5-phenyl-1,3,4-oxadiazole at ca 200°C in a sealed tube affords carbon dioxide, hydrogen sulfide, water, benzonitrile, benzamide, aniline, p-aminoacetophenone, indole, thioglycolic acid, 3-phenyl-2-thiohydantoin and 2-mercaptoquinazolinone. Furthermore pyrolysis of 2-(N-p-tolyl carboxamidomethylthio)5-phenyl-1,3,4-oxadiazole give rise to analogous products. A free radical mechanism has been suggested to account for the obtained products.
