Abstract

2-Aryl-1, 2, 3-triazoles were synthesized by cyclization of the corresponding glyoxal arylosazones, generated from commercial arylhydrazines. The deproto-metallation of 2- phenyl-1, 2, 3-triazole was attempted using different 2, 2, 6, 6-tetramethylpiperidino-based mixed lithium–metal (Zn, Cd, Cu, Co, Fe) combinations, giving results in the case of Zn, Cd, and Cu. The lithium–zinc combination was next selected to apply the deprotonation– ...
