A metal-free 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, but also high bromination selectivity. The possible mechanism and the role of the catalyst in this system have also been discussed.

The kinetics of oxidation of methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, s-butyl, dimethyl and trimethyl amines by Ce(4+) in moderately concentrated acid medium has been studied.The rate law for the oxidation of amines is: .A mechanism involving the attack of the oxidant at the nitrogen atom has been suggested.Ammonia and the corresponding aldehyde or ketone are the products of oxidation of aliphatic primary amines while formaldehyde and other amines are the products when dimethyl and trimethyl amine are used as the substrates.The thermodynamic parameters for the oxidation of amines are also presented.
