The reactions of benzene-1,2-diamine with 5-substituted 2-(alkylsulfanyl)-4-methylpyrimidin-6(1H)-ones and 2-(propylsulfanyl)- and 5-iodo-2-(propylsulfanyl)-3,4-dihydroquinazolines at 175-185A degrees C under solvent-free conditions unexpectedly afforded benzo[4,5]imidazo[1,2-a]pyrimidine, benzo[4,5]imidazo[2,1-b]-quinazoline, and 2,2'-(benzene-1,2-diyldiimino)bis[pyrimidin-4(3H)-ones]. The described reaction is the first example of synthesis of these heterocyclic systems by fusion of benzimidazole to pyrimidine or quinazoline and is likely to follow ANRORC mechanism.

2-propyl-thioquinozoline 4(3H) semicarbazone (PTQS) with Co(II), Ni(II) and Cu(II) metal ions. The complexes was characterized by molar mass, elemental analyses, IR electronic spectra, Molar conductivity and magnetic susceptibility assistance. On the above studies it was confirming that metal ions was coordinated with Carbonyl oxygen and azomethine nitrogen atom of semicarbazone moiety. The remaining valency
