4-N,N-Dimethylaminopyridine promoted selective oxidation of methyl aromatics with molecular oxygen

4-N,N-Dimethylaminopyridine (DMAP) as catalyst in combination with benzyl bromide was developed for the selective oxidation of methyl aromatics. DMAP exhibited higher catalytic activity than other pyridine analogues, such as 4-carboxypyridine, 4-cyanopyridine and pyridine. The sp3 hybrid carbon-hydrogen (C-H) bonds of different methyl aromatics were successfully oxygenated with molecular oxygen. The real catalyst is due to the formation of a pyridine onium salt from the bromide and DMAP. The onium salt was well characterized by NMR and the reaction mechanism was discussed.

Synthetic and mechanistic studies of indium-mediated allylation of imines in ionic liquids

Aldimines derived from aryl and non-enolizable aliphatic aldehydes were allylated with allyl bromide mediated by indium powder in [bpy][BF4] (bpy = N-butylpyridine) to give good yields of the corresponding homoallylic amines. Selective formation of monoallylated amines can be achieved by varying the amount of bromide ion additive in the form of [bpy][Br]. The transient organoindium intermediates, allylindium(I) and allylindium(III) dibromide formed in the reaction, were studied by NMR spectroscopy to explain the selectivity.     

New stationary phase for liquid chromatography with chemically bonded pinane ligand: synthesis and characterization by nuclear magnetic resonance and high-performance liquid chromatographic investigations

A new bicyclic phase for liquid chromatography was prepared by solution polymerization approaches. To introduce a C4 spacer the starting molecule 3-formylpinane was reduced to the alcohol followed by a substitution of the hydroxy group through a bromide. The obtained halide reacted with magnesium and allyl bromide to the 3-(but-3'-enyl)pinane which was hydrosilylated with trichlorosilane and finally immobilized to silica gels with different pore sizes using the technique of solution polymerization. To elucidate the structure of 3-(but-3'-enyl)pinane high-resolution two-dimensional nuclear magnetic resonance (NMR) spectra were carried out. The new phases were characterized, on the one hand by employing 13C and 29Si solid-state NMR spectroscopy and on the other hand, by separating a standard test mixture consisting of mainly monosubstituted aromatic compounds. The results achieved in chromatography were correlated with the information gained from 29Si CP/MAS NMR measurements.
