The monomeric title compound, C(9)H(6)BrCl(2)NO(3)S, has an envelope-shaped thia-zine ring with the S atom 0.879 (9) Å out of the mean square plane of the envelope. The π-π distances between the centroids of the heterocyclic rings are 4.191 (5) and 4.110 (5) Å. The closest intermolecular inter-actions between the O atoms of the carbonyl and sulfonyl groups with Br and Cl atoms are 2.987 (7) and...

In attempts to make octaphenyldibenzofuran (7) and octaphenyldibenzothiophene (8), 2,5‐dibromofuran (4) 2,5‐dibromothiophene (5), respectively, were heated with tetracyclone (2) under forcing conditions, but only single addition products, such as 2‐bromo‐4,5,6,7‐tetraphenylbenzofuran (10) 2‐bromo‐4,5,6,7‐tetraphenylbenzothiophene (12) observed. However, when 2,5‐dibromothiophene‐1,1‐dioxide (6)...

The title compound, C(19)H(10)BrCl(2)F(3)N(4)O, is an imine with an overall Y shape. The dihedral angles between the pyrazole ring and the methoxy- and trifluoromethyl-substituted benzene ring planes are 88.4 (2) and 65.8 (2)°, respectively.

The title compound, C(18)H(7)BrCl(2)F(3)N(5)O(2), is an L-shaped tricyclic imine. The pyrazole ring is essentially coplanar with the nitro-substituted benzene ring [dihedral angle = 3.6 (2)°] and approximately perpendicular to the trifluoro-methyl-substituted ring [dihedral angle = 88.5 (2)°].

This study aiming to determine the optimal conditions degrade an organophosphate pesticide diazinon (DZN) at low levels concentrations (μg.mL−1) and identify by-products generated. The degradation processes utilized were Fenton photo-Fenton. iron concentration [Fe2+], hydrogen peroxide [H2O2], solution pH are investigated parameters. Doehlert three-parameter experimental design was applied mode...

Previous studies showed that hyperbaric oxygen (HBO) promoted cell proliferation in hypoxic-ischemic (HI) neonate rats. Neural stem cells (NSC) existed in the brain lifelong and can be activated. This study was undertaken to assess whether HBO treatment promoted the proliferation of NSC and repaired the brain damage regardless of when it is started, thus to explore the therapeutic window of HBO...

In the title compound (5S,8R,9R,10R,13S,14S,17R,20R)-24-bromo-5β-cholane, C(24)H(41)Br, the fused-chair conformation of the cyclo-hexane A/B ring junction is cis with a 5β-H configuration.
