Abstract
A new procedure for the highly regioselective aerobic bromination of aromatic compounds
in the presence of copper-based nanoparticles (CuO/ZnO nanocatalyst) under reflux condition is described.
Mechanistic parameters are discussed and the plausible mechanism is proposed. Recyclability
of the CuO/ZnO nanocatalyst has also been explored upon aerobic bromination of aromatic compounds.

Abstract
An economic four-step synthesis of 2,6-dimethoxy-1,4-benzoquinone was achieved in 68% overall yield starting from aniline. The reaction sequence involved conversion to 1,3,5-tribromoaniline, deamination, methoxylation, and oxidation. The procedure is operationally simple and amenable to scale-up production.

Abstract
gem-Dihydroperoxides and 1,2,4,5-tetraoxanes were synthesised from aldehydes and ketones catalysed by heteropoly acid/NaY zeolite (HPA/NaY) as a new, effective and reusable solid catalyst using 30% aqueous hydrogen peroxide at room temperature. The reactions proceeded with high rates and excellent yields.
