The title compound, C(19)H(19)N(7)O(5), exhibits substitutional disorder of the ortho-nitro and cyano groups, with site-occupancy factors of 0.686 (7):0.314 (7). The two aromatic rings are essentially coplanar, with a dihedral angle of 6.6 (5)°. In the diethyl-amino group, the two ethyl groups lie on the same side of the amino-benzene plane. An intra-molecular N-H⋯N hydrogen bond links the amin...
The title compound, C9H10N4O, was obtained unintentionally by hydrolysis of 4-amino-1-benzyl-5-methyl-sulfanyl-1,2,4-triazolium tetra-fluoro-borate in the presence of sodium azide. In the crystal, alternating layers of polar amino-triazolinone and apolar benzene moieties are observed. N-H⋯O hydrogen bonds between the amino and carbonyl groups form infinite chains along [010]. These infinite cha...
A new tetra-dentate unsymmetrical Schiff base, C(15)H(10)N(4)O, has been synthesized from 4,5-dicyano-o-phenyl-enediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°. There are intra-molecular O-H⋯N and weak inter-molecular N-H⋯O and N-H⋯N inter-actions.
Modified proteins were detected in liver and bone marrow of mice following treatment with [(14)C]benzene. Stained sections were excised from one-dimensional and two-dimensional gels and converted to graphite to enable (14)C/(13)C ratios to be measured by accelerator mass spectrometry. Protein adducts of benzene or its metabolites were indicated by elevated levels of (14)C. A number of proteins ...
Revisiting the assembly of amino ester-based benzene-1,3,5-tricarboxamides: chiral rods in solution.
Some benzene-1,3,5-tricarboxamide (BTA) monomers derived from (l) α-amino esters self-assemble into long rods at millimolar concentrations, and display a strong chiral amplification effect. These rods are in competition with dimeric species.
Di(4-nitrobenzoyloxy)iodo]benzene (1), a hypervalent iodine compound, is easy to prepare and stable as solid, was shown be useful functional group transforming agent in this report. Oxidative synthesis of symmetrical disulfides from thiols the presence compound 1 alone performed 58–100% yields. Furthermore, ESI-MS demonstrated that premixing Ph3P yields corresponding acyloxyphosphonium, which c...
With the exception of the terminal benzene rings, the atoms in the title compound, C(20)H(18)ClN(3)O(2), are approximately coplanar (r.m.s. deviation = 0.0495 Å). The benzene/chloro-benzene rings form dihedral angles of 3.02 (4) and 41.59 (5)°, respectively, with this plane. The hy-droxy, amino and carbonyl groups all lie to the same side of the mol-ecule, enabling the formation of intra-molecu...
The title compound {systematic name: 3-chloro-5-[3-(dimethyl-amino)prop-yl]-10,11-dihydro-5H-dibenz[b,f]azepinium picrate}, C(19)H(24)ClN(2) (+)·C(6)H(2)N(3)O(7) (-), crystallizes with two independent cation-anion pairs in the asymmetric unit. The chlorimipraminium cation contains two benzene rings (one with a chloro substituent) fused to a V-shaped seven-membered azepine ring whose mean planes...
The title compound {systematic name: [8-(4-aminobenzoyl)-2,7-dimethoxynaphthalen-1-yl](4-aminophenyl)methanone}, C(26)H(22)O(4)N(2), possesses crystallographically imposed twofold symmetry, with two C atoms lying on the rotation axis. In the crystal, the mol-ecules inter-act through inter-molecular N-H⋯O hydrogen bonds between the amino and meth-oxy groups on the naphthalene ring systems and N-...
