چكيده لاتين :
Compound N2, N3, N7, N8, 1, 4, 5, 6, 9, 10-decaphenyltetradecahydrodipyrazino [2, 3-b: 2, 3-e] pyrazine-2, 3, 7, 8-tetraamine (4) was prepared by condensation of 1, 1י, 2, 2י-tetrakis (phenylamino) ethane (Id) and glyoxal in EtOH or i-PrOK Also, reaction of Id with glyoxal in equimolare in EtOH resulted 5,6-bis (ethoxy)-N2, N3 ,1, 4-tetraphenylhexahydro-2, 3-pyrazinediamine (5). The natures of products are sensitive to acidity, temperature and solvent. In acidic media, 4 and 5 are unstable and degraded to diimine 6.
