Abstract
The 5-aryihydrazone derivatives of rhodanine and isorhodanine were subjected to the action of hydrazine hydrate to afford the arylhydrazonomercaptomethyltriazolinthione and -triazolinone derivatives 3 and 4, respectively. Treatment of 1 with benzylamine afforded thioxalic acid dibenzylamide 5. On the other hand, treatment of 2 with the same reagent afforded the corresponding benzylamino derivatives 6. Alkylation of 1 and 2 with ethyl bromoacetate and chloroacetamide yielded the corresponding S-alkyl derivatives 7 and 8, respectively.
