Abstract

1, 3, 5-Trisubstituted 1, 2, 4-triazoles have been made in excellent yields by oxidative cycloaddition of arylhydrazones of benzaldehyde and butyraldehyde to aceto-, propio-, and acrylonitrile. Oxidation was achieved with the cation radicals thianthrenyl perchlorate (Th'+ C104-) and tris (2, 4-dibromophenyl) aminium hexachloroantimonate (Ar3N'+ SbC16-). The triazoles thus had a phenyl, p-nitrophenyl, or 2, 4-dinitrophenyl group in the 1-position, ...
