aerobic oxidative bromination of aromatic compounds in water has been developed. Hydrobromic acid is used as a bromine source and 2-methylpyridinium nitrate ionic liquid is used as a recyclable catalyst. Water is used as the reaction mediate. This is the first report of aerobic oxidative bromination using only catalytic amount of metal-free catalyst. This system shows not only high bromine atom economy

An efficient explosion-proof method was developed for the preparation of N,N-dialkylnitramines by treatment of dialkylammonium nitrates with a mixture of nitric acid and acetic anhydride in the presence of ZnCl2 in liduid or supercritical carbon dioxide.

were used to calculate the apparent molar volume (Vϕ), partial molar volume of solvent (V¯1) and solute (V¯2) at all studied temperatures. The limiting apparent molarvolumes (Vϕ0) are reported. The apparent molarexpansivity (Eϕ) of PILs at finite concentrations as well as at infinite dilutions are reported at 293.15 and 298.15 K. It is observed that water structure making effect exhibited by cations

azido-bridged coordinationpolymers, namely, [Ni(N3)2(Deeda)] (1), (DeaH)[Cu3(N3)7] (2), and (TeaH)[Cu4(N3)9] (3), where Deeda, (DeaH)+ and (TeaH)+ represent N,N-diethylethane-1,2-diamine, diethylammonium and triethylammonium, respectively. Magnetic studies revealed that they exhibit metamagnetism, spin glass and canted ferromagnetism, respectively, induced by different coordination modes of the azide
