Five different Nickel (II) complexes were prepared using a ONNO type Schiff base bis-N;N’(salicylidene)-1,3-propanediamine (LH2) and an ONO N(2-hydroxy)salicylaldimine (SAPH2) in the presence of NH3 or amine NiO nanoparticles obtained with thermal decomposition this air. The bases have been characterized by element analysis, IR spectroscopy, Thermogravimetry (TG), 1HNMR 13CNMR Mass Spectrometry...

In this study, a new series of 6-amino-1,3-dimethyluracil derivative with 6-(3-substituted N-benzylidene)-1,3-dimethyl pyrimidine-2,4-dione-6-yl derivatives which were synthesized by using one pot synthesis. The reaction and different aromatic aldehyde in ethanol yielded Schiff bases (1-6). the subsequent step )1-6) 2-mercaptoacetic acid, 2-chloroacetic acid 2-amino acetic acidn Tetrahydrofuran...

In this research, done synthesized a series of new 1,3-oxazepine-4,7-dione derivatives as D1-D3 compounds via using [2+5] cycloaddition reaction. Synthesized that have been bis azo groups [B1-B3] from 1,2-diaminobenzene coupling its diazonium salt with phenoxide anion 4-alkoxybenzaldehyde which Alkoxy was pentyl, hexyl, and Heptyl groups. These B1-B3 are condensed 4-Bromoaniline in Schiff bases...

antibacterial activity of the aerial extracts from xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. the best antibacterial results were obtained when methanol or the solvent mixture was used. the crude extract with the hi...

In this research, we synthesized oxazine and thiazine derivatives (3-6). These of chacone compounds (1 2) that from 4- hydroxyacetophenone aldehyde such as, 4-bromobenzaldehyde chlorobenzaldehyde. chalcone (1-2) reacted with urea to produce as 4-[4-amino-6-(4-subsutitedphenyl)-2H-1,3-oxazin-2-yl] phenol (3 4) thiourea 4-[4-amino-6-(4-subsutitedphenyl)-2H-1,3-thiazin-2-yl] (5 6). were characteri...

In this study heterocyclic compounds were prepared from thioxanthone derivatives and determined their structure by measuring melting point (M.P) infrared spectrum (FTR) 1HNMR for each one. These used testing antibacterial activity Streptococcus mutans, Staphylococcus saprophyticus, Enterococcus faecalis (Gram positive bacteria) Haemophilus influenzae negative bacteria). Prepared I,II,III,IIV sh...

A simple method for the synthesis of octahydroquinazolinone derivatives in the presence of BF3.SiO2 and Insecticide activity of these compounds against spodoptera litura was investigated to be comparable to commercial pyrethroid insecticides, Cypermethrin and Cyhalothrin. The structure of the isolated compounds was characterized by 1HNMR and FT-IR spectroscopy.The proposed method had some ad...
