An efficient methodology for bromination of polynitro stilbenes using molecular bromine as brominating agent over ZnO/H-beta-25 has been developed, which is conducted under mild condition, in good to high yield with excellent regio- and chemo-selectivities. Preliminary mechanistic studies have shown that this reaction most likely occurs via a noncovalent binding of molecular bromine to benzene ring...
The Baeyer–Villiger oxidation of cyclic ketones to the corresponding lactones using aqueous hydrogen peroxide as an oxidant over transition metal oxides was investigated. MoO 3 and WO 3 were found to exhibit higher catalytic activity than TiO 2 , Fe 2 O 3 , Co 3 O 4 , ZnO and ZrO 2 . The high catalytic activity was attributed to the interaction...
