| Abstract: | N,N′-Bis(2-aminophenyl)-1,2-ethanediamine is synthesized from 1,2-diaminoethane and 1-chloro-2-nitrobenzene in the presence of sodium carbonate and the product reduced by zinc dust and ammonium chloride. A novel stable dication is synthesized by reaction of N,N′-bis(2-aminophenyl)-1,2-ethanediamine and 2-pyridinecarboxaldehyde in the presence of manganese chloride in methanol. The X-ray structural analysis shows formation of the dication. |
