Nitro catechols via 2 hydroxyl group and a nitro group have a wide range of functions including reagents form stable complexes with more than 40 elements in the fields of analytical chemistry, biochemistry, coordination chemistry, environmental chemistry, atrium exploration, organic chemistry, pharmacy, etc. Moreover, the nitro to amine recovery has a potential function in different fields. In ...

2014 A transition between a smectic A phase and a smectic A antiphase (SÃ) is observed for the first time in a pure compound : the nitrobenzoyloxybenzoate of heptylphenyl. So far, the anomalies of periodicities which are connected to this type of transition were only detected in cyano systems. Moreover, the solid phase of the inferior homologue of this nitro series is surprisingly influenced by...

The title zinc bis(thiosemicarbazone) complex, [Zn(C 22 H 17 N 4 O 2 S) ], comprises two , S -donor anions, leading to a distorted tetrahedral donor set. resultant five-membered chelate rings are nearly planar and form dihedral angle of 73.28 (3)°. configurations about the endocyclic- exocyclic-imine bonds Z E respectively, that ethylene bond is . major differences in conformations ligands seen...

a series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. the chemical structures of the compounds were elucidated by ft-ir, 1h-nmr and mass spectra. all newly synthesized compounds were evaluated for their antimycobacterial activities against mycobacterium tuberculosis h37rv using the microplate alamar blu...

Mutagenic activity and DNA interca]ation were examined for 9-aminoacridine (9-AA) and its deriyatiyes. Introduction of a nitro group into the 9-AA molecule was found to enhance the actiyity enormously as was detected by the Ames test. Acetylation of amino group at 9-position of acridine ring inhibited the intercalation, the frameshift activity disappearing. Rat liyer S9 conyerted 9-AA metabolic...

Synthesis of 2-(4-Acetyl-phenyl)-4-nitro-isoindole-1, 3-dione chalcones were performed by fusion 3-nitro phthalic anhydride with p-aminoacetophenone. Then the later was grinded different aromatic aldehydes in presence sodium hydroxide to produce new derivatives A3-10 without using any solvent formation N-arylphthailimide confirmed FTIR,1HNMR, 13CNMR spectroscopy and all final compounds tested f...

a series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. some of the tested compounds were active against staphylococcus aureus, staphylococcus epidermidis, bacillus subtilis, clostridium difficile, aspergillus niger and cryptococcus neoformans.

Molecular devices are reported utilizing active self-assembled monolayers containing the nitroamine @28-amino-4,48-di~ethynylphenyl!-58-nitro-1-benzenethiolate# or the nitro compound @4,48-di~ethynylphenyl!-28-nitro-1-benzenethiolate# as the active components. Both of these compounds have active redox centers. Current–voltage measurements of the devices exhibited negative differential resistanc...
