synthesis, characterization and study biological activity of some 1,2,4-triazin heterocyclic derivatives

A series of some new heterocyclic compounds containing triazin derivatives have been synthesized in many steps sequence. triazine derivatives were prepared through reacting benzil with semicarbazide or thiosemicarbazide to form 5,6-diphenyl-1,2,4-triazin-2(3h)one,5,6-diphenyl-1,2,4-triazine-2(3h)thione, respectively. a hydroxymethylation reaction has been made to the amide group. the hydroxyl group was replaced by azide group. a different substituted triazine rings have been formed using different reagents. the structures of the newly prepared derivatives were identified through more than one technique like (ft-ir, 1h-nmr, and 13c-nmr) for all derivatives.
