Abstract:
This thesis is concerned with the synthesis and characterization of two new series : 1. A series of heterocyclic compounds which have been prepared from the reaction of urea, thiourea , hydroxylamine and hydrazine hydrate with compound of prepared chalcone in the presence of sodium hydroxide following table shows these compounds : symbol Name and Structure 1A O N O2N NO2 3,5 - bis(4 - nitrophenyl) - 4,5 - dihydroisoxazole 1B HN N O2N NO2 3,5 - bis(4 - nitrophenyl) - 4,5 - dihydro - 1H - pyrazole O2N NO2 N N OH 4,6 - bis(4 - nitrophenyl)pyrimidin - 2 - ol O2N NO2 4,6 - bis(4 - nitrophenyl)pyrimidine - 2 - thiol 2. A series of dinitrone compound that described by the following forms : Symbol Structure These two series identified by IR , 1H NMR and mass spectroscopic techniques.The biological activity of the prepared compound was investigated against two types of germs (Gram positive and negative) and it has found that these compound the study showed that some of these compounds effective against bacteria positive without negative , as the focus was to measure the minimum inhibitory (MIC) to them.
