Synthesis of Certain 3-(Alkyl/Arylthioureido)-5-Alkylimino-4-Alkyl-1,2,4-Δ2-Thiadiazolines

Abstract

Condensation of 5-alkylimino-3-amino-4-alkyl-1 ,2,4-Δ² -thiadiazolines
and alkyl/aryl isothiocyanates in a basic medium yields
3-( alkyl/aryl thioureido)-5-alkylimino-4-alkyl-1 ,2,4-Δ² -thiadiazolines.
Their structures have been established by chemical analysis
and spectral data. The steric effects of alkyl or aryl groups do not
affect the course of the reaction.
