2-Nitro-p-phenylene dibenzenesulfonate
In the title compound, C(18)H(13)NO(8)S(2), the nitro-phenyl ring forms dihedral angles of 46.67 (7) and 75.40 (6)° with the phenyl rings. The nitro group makes a dihedral angle of 26.13 (8)° with the attached ring. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل2-Nitro-p-phenylene bis(toluenesulfonate)
In the mol-ecule of the title compound, C(20)H(17)NO(8)S(2), the two toluene rings are oriented at a dihedral angle of 3.65 (4)°, while the nitrophenyl ring is oriented at dihedral angles of 44.39 (3) and 47.44 (3)° with respect to the toluene rings. An intra-molecular C-H⋯O hydrogen bond results in the formation of a five-membered ring, which adopts an envelope conformation. In the crystal str...
متن کاملBioassay of 2-nitro-p-phenylenediamine for possible carcinogenicity.
A bioassay for the possible carcinogenicity of 2-nitro-p-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. 2-Nitro-p-phenylenediamine was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty animals of each sex and species were placed on test as controls. The high and low dietary concentrations of 2-ni...
متن کاملSynthesis and properties of poly(p-phenylene vinylene) derivatives with hyperbranched structure and containing a nitro substituent
ABSTRACT In order to improve efficiency, processability, and stability, two groups of novel poly(p-phenylene vinylene) (PPV) derivatives (P1-P3 and P4-P6) with hyperbranched structure and containing a nitro substituent were synthesized via a Gilch reaction in different monomer ratios. The properties of the polymers were investigated by using UV-Vis absorption, fluorescence spectroscopy, cyclic ...
متن کاملDiethyl N,N′-(p-phenylene)dioxamate
In the crystal structure, the mol-ecule of the title compound, C(14)H(16)N(2)O(6), is located on an inversion centre. The amide -NHCO- plane makes a dihedral angle of 34.08 (9)° with the benzene ring. The mol-ecules are connected via inter-molecular O-H⋯N hydrogen bonds into a two-dimensional network parallel to the bc plane. An intramolecular N-H⋯O hydrogen bond is also observed.
