Synthesis of 5-aryl-2,4-dialkyl-3H-1,2,4-triazole-3-thione (Process for preparing 5-Aryl- 4-Triazole-3-Thiones)

摘要

The 5-aryl-2,4-dialkyl-3H-1,2,4-triazole-3-thione of formula (I) is prepared by mixing a dialkylthiomethylcarbazide of formula (1) , And this mixture is reacted with benzoyl chloride of the formula (2).;Wherein R is halogen, alkyl or alkoxy, n is 1 or 2, and R ₂ and R ₃ are alkyl.
