4-Bromobenzoyl 4-bromobenzoate monohydrate

In the title compound, C(14)H(8)Br(2)O(3)·H(2)O, the organic and water mol-ecules both have crystallographically imposed C(s) symmetry. The dihedral angle between the aromatic rings is 45.76 (11)°. In the crystal structure, inter-molecular C-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the a axis. No π-π stacking inter-actions are observed in the crystal structure.

[2-(4-Methylbenzoyl)phenyl](4-methylphenyl)methanone

The asymmetric unit of the title compound, C(22)H(18)O(2), contains one half-mol-ecule, the complete mol-ecule being generated by the operation of a crystallographic twofold rotation axis. The carbonyl group and the two C atoms attached to it forms inter-planar angles of 23.67 (7)° with the methyl-substituted phenyl ring and 50.74 (8)° with the central ring. In the crystal, mol-ecules are linke...

[2,7-Dimethoxy-8-(4-methylbenzoyl)-1-naphthyl](4-methylphenyl)methanone

In the title compound, C(28)H(24)O(4), the two 4-methyl-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the dihedral angle between the two phenyl rings being 9.64 (7)°. The dihedral angles between the two phenyl rings and the naphthalene ring system are 71.82 (6) and 71.58 (6)°. In the crystal, inter-molecular C-H⋯O inter-actions between...

Characterization of bacterial consortia capable of degrading 4-chlorobenzoate and 4-bromobenzoate under denitrifying conditions.

4-Chlorobenzoate and 4-bromobenzoate were readily degraded in denitrifying enrichment cultures established with river sediment, estuarine sediment or agricultural soil as inoculum. Stable denitrifying consortia were obtained and maintained by serial dilution and repeated feeding of substrates. Microbial community analyses were performed to characterize the 4-chlorobenzoate and 4-bromobenzoate d...

significance as calcium-channel modulators in the treatment of cardiovascular diseases, such as hypertension, cardiac arrythmias or angina.1 In recent years, interest has also been focused on aza-analogs of dihydropyridines, such as dihydropyrimidines, which show a very similar pharmacological profile to that of dihydropyridine calcium channel modulators.2 In a continuation of these studies, ri...
