چکیده
In the title compound, C(8)H(6)Br(4), intra-molecular C-H⋯Br hydrogen bonds generate two S(6) rings. The two geminal bromine-atom substituents point to opposite sides of the aromatic ring system. In the crystal, mol-ecules are linked by inter-molecular π-π inter-actions with centroid-centroid distances of 3.727 (9) and 3.858 (9) Å.

In the two-dimensional title coordination polymer, [Ni(C(8)H(3)BrO(4))(C(14)H(14)N(4))(H(2)O)](n), the Ni(II) atom adopts a distorted octa-hedral geometry, being ligated by three O atoms from two different 5-bromo-benzene-1,3-dicarboxyl-ate ligands, two N atoms from two 1,2-bis-(imidazol-1-ylmeth-yl)benzene ligands and one coordinated water mol-ecule. The Ni atoms are bridged by the 5-bromo-ben...

A catalytic amount of 1,2-bis(diphenylphosphino)benzene (DPPBz) achieves selective cleavage of sp(3)-carbon-halogen bond in the iron-catalysed cross-coupling between polyfluorinated arylzinc reagents and alkyl halides, which was unachievable with a stoichiometric modifier such as TMEDA; the selective iron-catalysed fluoroaromatic coupling provides easy and practical access to polyfluorinated ar...
