Abstract
Oxidation of certain 1-alkylthioureas has been found to follow
the overall pattern as observed in the case of 1-aryl and 1-aryl-3-
alkyl substituted thioureas. The primary product in all cases is the
corresponding bis(substituted formarnidine) disulphide salt which
eliminates an atom of sulphur affording the related monosulphide
salt which rearranges into the isomeric arnidinothiourea These on
further oxidation form the corresponding 1,2,4-thiadiazolines. Their
structures have been established by chemical degradation and spectral,
studies.
