Kinetic-spectrophotometric method for the determination of trace amounts of bromide in seawater [PDF]
A novel simple, sensitive and rapid kinetic-spectrophotornetric method is proposed for the determination of trace amounts of bromide. The method is based on its catalytic effect on the oxidation of methylene blue (MB) by hydrogen peroxide in strongly ...

Infinite stacking of alternating polyfluoroaryl rings and bromide anions [PDF]
The crystal structure of 1-(4-bromo-2,3,5,6-tetrafluorophenyl)-3-benzylimidazolium bromide comprises columns of parallel bromotetrafluorophenyl rings with an interplanar distance of 6.936(6) Å separated by bromide ...

On the importance of π–π stacking and cation–anion interactions in the construction of non-centrosymmetric networks of bromide salts of imidazolium cations bearing arene and polyfluoroarene rings [PDF]
The salt 1-(2,3,5,6-tetrafluoropyridyl)-3-benzylimidazolium bromide crystallizes in the non-centrosymmetric space group Pna2₁. The structure arises from π–π stacking between the benzyl and tetrafluoropyridyl groups of the cations and cation–bromide ...

Scalable synthesis of ionic liquids: comparison of performances of microstructured and stirred batch reactors [PDF]
A range of alkylpyridinium bromide ionic liquids have been synthesized in a stirred reactor at multigram scale and characterized by physical methods (viscosity, conductivity, melting point, electrochemical window, and water content).

SANS studies of liquid crystalline microemulsion gels [PDF]
We have investigated by small-angle neutron scattering (SANS) the ternary system containing water, alkane and the surfactant mixture benzyltetradecyldimethylammonium chloride and tetradecyltrimethylammonium bromide, which we have found to form a cubic ...

Intramolecular pi-pi stacking interactions in 2-substituted N,N-dibenzylaziridinium ions and their regioselectivity in nucleophilic ring-opening reactions [PDF]
The ring opening of 2-substituted N,N-dibenzylaziridinium ions by bromide is known to occur exclusively at the Substituted aziridine carbon atom via ail S(N)2 mechanism, whereas the opposite regioselectivity has been observed as the main pathway for ring
