2-Bromo-1-(1H-pyrazol-4-yl)ethanone: versatile precursors for novel mono-, bis- and poly{6-(1H-pyrazol-4-yl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines}
A simple synthesis of novel mono-, bis- and poly{6-(1H-pyrazol-4-yl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines} is reported. The formation of the target compounds was achieved by the reaction of 2-bromo-1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone with the appropriate aminotriazolethiol or by the r...

Summary: | A simple synthesis of novel mono-, bis- and poly{6-(1H-pyrazol-4-yl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines} is reported. The formation of the target compounds was achieved by the reaction of 2-bromo-1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone with the appropriate aminotriazolethiol or by the reaction of 6-pyrazolyl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine-3-thiol with the appropriate di- and poly(bromo) compounds. The structures of the newly synthesized compounds were established by spectroscopy and elemental analyses.
