Charge-transfer (CT) complexes of pyrimidine Schiff bases, derived from condensation of 2-aminopyrimidine and substituted benzaldehydes, with some aromatic polynitro compounds were prepared and investigated using IR, UV, visible and 1H NMR spec

Chloroacetyl pyrimidine was synthesized and reacted with both aromatic amines and hydrazine hydrate. Hydrazide was reacted with β-dicarbonyl compounds and also with different acid anhydrides. 2-Amino-pyrimidine afforded new Schiff's bases which were cyclized with thioglycolic acid and thiolactic acid. Thiosemicarbazido derivatives were cyclized to give thiadiazole which gave Mannich bases. Some of the newly prepared compounds were biologically tested as antimicrobials.

The 70 eV electron impact mass spectra of some para-substituted N-heteroaryl benzylamines, synthesized through the corresponding Schiff bases, are reported.Typical fragmentation patterns are discussed with the aid of mass analyzed ion kinetic energy spectra and exact mass measurements.The compounds are relatively stable under electron impact, the molecular ion being the base peak or the second most intense ion in the spectra.The dominating breakdown process is the benzylic cleavage, that gives rise to the base peak in some of the investigated compounds and to the second intense peak in others.
