Abstract Novel derivatives of Schiff bases with diazene bonds and six new 2,5-disubstituted pyrimidine derivatives were synthesized by reaction of 2-substituted trimethinium salts with 4-aminoazobenzene or benzamidine hydrochloride, respectively, by a simple method and using inexpensive reagents. The purity and molecular structure of the new compounds were determined by elemental analysis, mass spectrometry, infrared, ultraviolet/visible, as well as proton nuclear magnetic resonance (1H NMR) and carbon-13 nuclear magnetic resonance (13C NMR) spectroscopy.
