RESUMO

Bis-[4-alquil/aril-5-tia-1,2,4-triazóis] foram preparados pela fusão de diácidos e tiosemicarbazidas, pela condensação de hidrazidas ácidas aromáticas com isotiocianato. A alquilação quimiosseletiva destes bis-[4-alquil/aril-5-tia-1,2,4-triazóis] com 1,ômega-dihaloalcanos na presença de hidróxido de potássio em metanol aquoso, proporcionou N-alquil/aril tiatriazolofanos inéditos.
