The title compounds, tetra-butyl-ammonium chloride-1,1'-(1,2-phenyl-ene)bis-(3-m-tolyl-urea) (1/1), C16H36N+·Cl-·C22H22N4O2 or [(n-Bu4N+·Cl-)(C22H22N4O2)] (I) and tetra-butyl-ammonium bromide-1,1'-(1,2-phenyl-ene)bis-(3-m-tolyl-urea) (1/1), C16H36N+·Br-·C22H22N4O2 or [(n-Bu4N+·Br-)(C22H22N4O2)] (II), both comprise a tetra-butyl-ammonium cation, a halide anion and an ortho-phenyl-ene bis-urea mo...

1-butyl-3-methylimidazolium bromide ([bmim]br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by nabro3 in excellent yields under neutral conditions.

BACKGROUND Clozapine is the only medication licensed for the treatment of resistant schizophrenia in the UK. Although efficacious, a common and unpopular side effect of clozapine treatment is clozapine-induced hypersalivation (CIH), which can contribute to non-adherence. The standard treatment for CIH in the UK is hyoscine hydrobromide but this may aggravate cognitive deficits in patients with ...

The redetermined, low temperature (150 K), structure of tetra-n-butyl-ammonium bromide, (C(4)H(9))(4)N(+)·Br(-), has been found to be merohedrally twinned via twin law -1 0 0, 0 - 1 0, 1 0 1. The structure was previously determined, with low precision, no inclusion of H atoms and only the bromide ion refined with anisotropic displacement parameters, by Wang et al. (1995 ▶). Mol. Cryst. Liq. Cry...

BACKGROUND Unripe cervix prevents entering the endometrial cavity during intrauterine procedures. Mechanical dilatation of cervical canal might cause undesirable complications. OBJECTIVE To investigate the substitute of mechanical intervention with chemical treatment by administering hyoscine to patients. MATERIALS AND METHODS Sixty non-pregnant women, 20-70 years of age, with a closed cerv...

X-ray absorption spectroscopy (XAS) has been used to unveil the bromide ion local coordination structure in 1-alkyl-3-methylimidazolium bromide [C(n)mim]Br ionic liquids (ILs) with different alkyl chains. The XAS spectrum of 1-ethyl-3-methylimidazolium bromide has been found to be different from those of the other members of the series, from the butyl to the decyl derivatives, that have all ide...
