    An Anomalous Course of The Condensation of 1,5-Diaryl-3-formazyl glyoxylic Acids with o-Phenylenediamine

  • Original language description

    A condensation of 1,5-diaryl-3-formazyl-glyoxylic acids with o-phenylenediamine did not afford 1,2-dihydro-3-(1,5-diaryl-3-formazyl)-quinoxaline-2-ones, but 1,5-diaryl-3-(2-benzimidazol-2-yl)-formazanes with simultaneous elimination of formic acid. Formazanes were transformed by reductive splitting to benzimidazole-2-carboxamide arylhydrazones. Oxidative cyclization of mentioned formazans tetrazolium salts were prepared.
