The crystal structure of the title compound, C14H14N2O, determined at 293 K, shows that the molecule is approximately planar in the solid state and that the aromatic rings have a trans configuration with respect to the azo ...

The crystal structure of the title compound, 6-tert-butyl-2-(2-chlorophenyldiazenyl)-4-methylphenol C17H19Cl-N2O, determined at room temperature, shows that the molecule is essentially planar, as found for other azobenzene ...

The title compound, C15H16N2O, has a trans configuration with respect to the diazene double bond, and is approximately planar in the solid state. The dihedral angle between the planes of the two aromatic rings is 8.33 ...

The synthesis and characterisation of o,o'-dihydroxyazo dyes and their chromium complexes is described by IR, UV-VIS, H-1 NMR spectroscopic techniques, magnetic susceptibility, thin-layer chromatography and elemental ...

The C-13-NMR spectra of the azo dyes which were synthesized by reacting substituted benzenediazonium chloride with derivatives of some phenol have been measured. The spectral data of these compounds were described considering ...

Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlrocyclotriphosphazene and 4-hydroxyazo compounds such as 4-hydroxyazobenzene, 4'-ethyl-4-hydroxyazobenzene, 4'-tertbutyl-4-hydroxyazobenzene, ...

2,6-Dimethyl-4-(4-tert-butylphenyidiazenyl)phenyl acrylate (C21H24N2O2), containing an acryloyloxy group, first 2,6-dimethyl-4(4- tert-butylphenyldiazenyl)phenol was prepared by reacting 4-tert-butylbenzenediazonium salt ...

The synthesis of some novel azo dye (II-VII) derivatives of substituted phenols have been carried out by reacting phenol, 2,6-dimethylphenol, 2-tert-butylphenol, 4-tert-butylphenol, 2-tert-butyl-4-methylphenol, and ...

Thermal behaviour of six azo dyes containing steric hindered groups such as tert-butyl, sec-butyl and isopropyl, were investigated by means of thermogravimetry (TG), differential thermal analysis (DTA) and differential ...
