چکیده
The title compound, C(7)H(4)Br(2)O(3), has an intra-molecular O-H⋯O=C hydrogen bond and aggregates to form hydrogen-bonded dimers via O-H⋯O inter-actions. The formation of zigzag one-dimensional mol-ecular tapes via C-H⋯Br inter-actions and π-π stacking inter-actions (inter-planar separation = 3.42 Å) completes the crystal structure.

The title mol-ecule, C(22)H(22)Br(4)O(2)S(2), is centrosymmetric with an inversion centre located at the centre of the benzene ring. The 3,5-dibromo-thio-phene groups are twisted relative to the benzene ring, making a dihedral angle of 41.43 (9)°.
متن کاملDifferential modulation of glutamatergic transmission by 3,5-dibromo-L-phenylalanine.
An increasing body of evidence supports the hypothesis that diminished function of N-methyl-D-aspartate (NMDA) receptors and the associated increase in glutamate release and overstimulation of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate receptors are critical elements of the pathophysiology of schizophrenia. Here, we describe a halogenated derivative of the aromatic ...

The title compound, C(15)H(12)Br(2)N(2)O(3), was synthesized by the reaction of 3,5-dibromo-2-hydroxy-benzaldehyde with an equimolar quantity of 2-methoxy-benzohydrazide in methanol. The dihedral angle between the two benzene rings is 3.4 (2)° and intra-molecular O-H⋯N and N-H⋯O hydrogen bonds are observed in the mol-ecule. The crystal studied was an inversion twin with a 0.513 (19):0.487 (19) ...

In the title complex, [Cu(C(16)H(11)Br(2)NO(4))(C(3)H(7)NO)](2), there are two unique mol-ecules in the asymmetric unit. Each Cu(II) atom is coordinated by two O atoms and one N atom from the tridentate ligand L(2-) [LH(2) = (E)-2-(3,5-dibromo-2-hydroxy-benzyl-idene-amino)-2-(4-hydroxy-phenyl)acetic acid] and the O atom of a dimethyl-formamide mol-ecule to give a slightly distorted square-plana...
متن کاملSynthesis of tetraarylpyridines by chemo-selective Suzuki-Miyaura reactions of 3,5-dibromo-2,6-dichloropyridine.
Chemoselective Suzuki-Miyaura reactions on 3,5-dibromo-2,6-dichloropyridine were studied. The optimized reaction conditions allow for the facile access of 3-aryl- and 3,5-diarylpyridines in good yields. Suzuki-Miyaura reactions of the selectively synthesized 2,6-dichloro-3,5-diarylpyridines gave the corresponding 2,3,5,6-tetraarylpyridines, containing two different aryl moieties.
