An anomalous course of the condensation of 1,5-diaryl-3-formazyl glyoxylic acids with o-phenylenediamine. A simple synthesis of some benzimidazole-2-carboxamidarylhydrazones
Original language description
The condensation of 1,5-diaryl-3-formazylglyoxylic acids 1 with o-phenylenediamine did not afford 1,2-dihydro-3-(1,5-diaryl-3-formazyl)-chinoxalin-2-ones 2, but actually 1,5-diaryl-3-(2-benzimidazol-2-yl)-formazanes 7 with simultaneous elimination of formic acid. Formazans 7 were transformed by reductive splitting into benzimidazol-2-carboxamid arylhydrazones 10.
