Pyrolysis of 2-arylimino-3-arylthiazolidin-4-one gives rise to water, aniline, acetanilide,
azobenzene, benzonitrile, p-toluonitrile, indole, benzthiazole, 6-methylbenzthiazole, thioglycolic
acid, phenylisothiocyanate, p-tolylisothiocyanate, thiocarbanilide, N-phenyl-N-ptolylthiourea,
p-aminoacetophenone and N-phenylbenzimidazole.
A free radical mechanism has been suggested to account for the formation of the
products.
