an ion imprinted polymer (iip) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of sr (ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde) (nipaf). the sorbent was characterized by fourier transform infrared spectroscopy and was used for solid ph...

In the structure of the title compound (N2CP2MBA), C(14)H(12)ClNO, the conformations of the N-H and C=O bonds are trans to each other. Furthermore, the conformation of the N-H bond is syn to the ortho-chloro group in the aniline ring and the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring, similar to what is observed in 2-chloro-N-(2-chloro-phen-yl)benzamide and 2-methyl-N-p...

Enhancement of aniline hydroxylation by Habu snake venom was studied in vitro. The fraction which was isolated from Habu venom through column chromatography caused the enhancement of aniline hydroxylation of hepatic microsomes obtained from untreated rats. This fraction was heat stable and free from phospholipase activity. Enhancement of aniline hydroxylation was not clear in crude Habu venom o...

The interactions of aniline with soil at an industrial spill site were investigated. Sorption of aniline to the soil was observed to occur through a two-step mechanism. The first step was an ion exchange process with the protonated amine serving as an organic cation. This step was influenced by solution pH and ionic composition. The second step was covalent bonding most likely with quinone moie...

A series of linear and branched high-spin diand tri(cation radical)s (12•2+, 72•2+, 33•3+, 43•3+, and 93•3+) has been prepared by oxidation of the corresponding meta-para aniline oligomers. The oligo(cation radical)s are stable under ambient conditions. The formation and properties of the cation radicals has been studied in detail by cyclic voltammetry and UV-vis-near IR spectroscopy. ESR spect...

The mol-ecular structure of the title compound, C18H21N3S, shows a twisted conformation with a dihedral angle of 67.45 (4)° between the aromatic ring planes and an N-C-C-S torsion angle of -5.01 (13)°. The imidazolidine ring and the aniline moiety make a dihedral angle of 56.03 (4)° and the asscociated C-N-C angle is 125.71 (10)°. The guanidine-like C=N double bond is clearly localized, with a ...

In the title compound, C(14)H(14)N(2)O(2), the dihedral angle between the two benzene rings is 9.67 (10)°. Two intra-molecular O-H⋯N and N-H⋯N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, N-H⋯O hydrogen bonds link neighboring mol-ecules. Mol-ecules are also stacked in a head-to-tail fashion along the c axis th...

In the title compound, C(13)H(12)N(2)O(2)S, the dihedral angle between the benzene and thio-phene rings is 36.72 (8)°. An inter-molecular C-H⋯π inter-action contributes to the stability of the crystal structure.

In the title compound, C(19)H(15)N(3)S·H(2)O, the benzothia-zole ring system forms a dihedral angle of 7.22 (1)° with the benzene ring and the benzene ring forms a dihedral angle of 80.89 (1)° with the pyridine ring. An intra-molecular N-H⋯O inter-action is present. The crystal structure is stablized by inter-molecular O-H⋯N hydrogen bonds, π-π [centroid-centroid distances = 3.782 (1), 3.946 (1...
