A series of 2-cyclohexylideneamino-5-arylimino-3-oxo-1,2,4-thiadiazolidines (3a-e) have been synthesised by the oxidative cyclodehydrogenation of the related 1-aryl-5-(cyclohexylideneamino)-2,4-thiobiurets (1a-e) obtained by the condensation of cyclohexanonese-micarbazone and aryl isothiocyanates. Compounds 3a-e have also been obtained alternatively by the oxidative debenzylation of the corresponding 1-aryl-5-(cyclohexylideneamino)-2-5-benzyliso-2,4-thiobiurets (2a-e) with bromine in chloroform. The latter being obtained by the benzylation of (1a-e).
