SYNTHESIS OF SUBSTITUTED-Δ2-1,2,4-TRIAZOLIN-5-ONES AND S-SUBSTITUTED ISOTHIOBIUREAS FROM 1-ARYL/ALKYL-6-PHENYL-2-THIOBIUREAS
摘要:
Reaction of 1-aryl/alkyl-6-phenyl-2-thiobiureas 1 with BnCl and BuI in neutral medium at reflux temperature resulted in the formation of the S-alkylated isothiobiureas 2 and 1,2,4-triazolin-5-one derivatives 3. A convenient route to 2 is also reported.
