Abstract
Novel 6-aryl-1,4-diazepinium and 3-aryl-hexahydro-1H-benzo-[b-1,4]-diazepinium salts (with aryl and heteroaryl = 1-quinilinio, 3,5-dimethylpyridinio, 4-phenyl phenyl, 3,4,5-trimethoxyphenyl, and 1,4-phenylene) were synthesized mostly by reactions of 1,2-diamines with 3-aryl and 3-heteroaryl-1,5-diazapentadienium salts. The ultraviolet spectral behavior of these compounds was examined in acetonitrile. Elemental analysis, infrared, 1H NMR, 13C NMR, and mass spectra confirmed the molecular structure of the newly synthesized compounds.
