المستخلص: This study was included the preparation of a series of compounds heterogeneous Nitrones. Novel compounds were resulting from the reaction between azo compounds and hydroxylamine compounds through several steps. | the first step was synthesis of a new azo compounds for 2-aminopyridine includes (2a, 2b, 2c, 2d) by configuration the diazonium salt, which in turn enters the reaction of duplication with these aldehydes (2-nitro benzaldehyde, 4-dimethylamino benzaldehyde, 4-chloro benzaldehyde and 4-hydroxy benzaldehyde) respectively. | The second step was included the preparation of hydroxylamine compounds, (N-phenyl hydroxylamine and N-p-toluidine hydroxylamine) were reduced depending on the methods published in the literature. | The third step included the reaction between N-phenyl hydroxyl amine and azo compounds to gave nitrones compounds first set (3a, 3b, 3c, 3d) respectively. | Also we prepare nitrones compounds by the reaction between azo compounds with N-p-toluidine hydroxylamine to give Nitrones compounds second set (3e, 3f, 3g, 3h). | It has been identified the both novel azo-aldehydes and nitrones compounds by using infrared spectroscopy (FT-IR), spectrum NMR proton (1H-NMR), spectrum NMR carbon (13C-NMR) and mass spectrometry (Mass Spectra ) as well as we measured the Melting point for the preparing compounds. | We also Study the effectiveness of biological compounds of the prepared compounds inhibited the growth of some bacteria positive and negative gram, it has shown some compounds to be effective in killing or inhibition of these germs. | next table shows the compounds prepared in this study.
