چکیده
The mol-ecule of the title compound, C(14)H(8)Br(2), is almost planar [maximum deviation 0.0355 (7) Å] and possesses crystallographic twofold (C2) symmetry. In the crystal, the mol-ecules form face-to-face slipped anti-parallel π-π stacking inter-actions along the c axis with an inter-planar distance 3.471 (7) Å, centroid-centroid distances of 3.617 (5)-3.803 (6) Å.

Efficient Synthesis of a Range of 1-Hydroxy-2-(1-Alkyloxymethyl)-9,10-Anthraquinone Derivatives
Five new 1-hydroxy-2-(1-alkyloxymethyl)-9,10-Anthraquinones (9a-e) have been prepared. Selective nitration of 2-methyl-9,10-anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-2-methyl-9,10-anthraquinone in good yield as the key intermediate. Reaction with dimethylsulphate/K2CO3 and subsequen...

A one pot four-component reaction of 9,10-phenanthraquinone, aromatic aldehyde, aniline, and ammonium acetate was designed for the preparation of tetrasubstituted imidazoles (phenanthro[9,10-d]imidazole) derivatives in the presence of SBA-Pr-SO3H as a mesoporous solid acid catalyst. Phenanthro[9,10-d]imidazole derivatives were produced by the use of this technique in short reaction times and go...
متن کامل3,6-Dibromophenanthrene
The phenanthrene ring in the title compound, C(14)H(8)Br(2), is approximately planar [maximum deviation = 0.039 (3) Å]. In contrast, the two bromo atoms are displaced slightly from the phenanthrene plane [maximum deviation = 0.1637 (3) Å]. In the crystal, the mol-ecules adopt a herringbone-like arrangement and form face-to-face slipped π-π stacking inter-actions along the b axis, with an inter-...

Treatment of 5,8-dihydroxy-1-tetralone (9) with either 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in refluxing benzene or silver (I) oxide in refluxing 1,4-dioxane afforded juglone (5-hydroxy-1,4-naphthoquinone) (1) in good yield. With manganese dioxide in dioxane the tetralone gave a mixture of juglone and naphthazarin (5,8-dihydroxy-1,4-naphthoquinone) (3), the proportion of naphthazarin...
