Some interesting observations involving reaction of excess of benzylamine and isoperthiocyanic acid (Ia), the so-called isothiocyanate sulphides (Ib-If) and isothiocyanate oxides (II) have been reported.In these reactions 5-alkyl/arylimino-2,4-dialkyl/aryl-3-thio-1,2,4-thiadiazolidines (III) and 5-arylimino-2,4-dialkyl/aryl-3-oxo-1,2,4-thiadiazolidines (VI) have been isolated.In all these reactions, elemental sulphur initially formed acts as a potential oxidant in the oxidative cyclisation of intermediates, viz., 2,4-dithiobiurets (IV) and 2-thiobiurets (VII).
