Title
Vanadium phosphorus oxide modified by silver doping: A highly effective catalyst for allylic oxidation of cycloolefins
Abstract

Allylic oxidation of cycloolefins was carried out over Ag-VPO catalyst using tert-butyl hydroperoxide (TBHP) as oxidant in argon atmosphere, under our reaction conditions, attack of the activated C–H bonds was preferred instead of the epoxidation of C=C bond and corresponding α, β-enones were obtained as the main products. It is a high yielding, safe and eco-friendly method.

Graphical abstractAn efficient allylic oxidations of cycloolefins over silver doped VPO catalyst in an environmentally benign oxidation protocol involving aqueous tert-butyl hydroperoxide in argon atmosphere was reported. Also, a redox mechanism was proposed basing on the cyclohexene.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Silver doped vanadium phosphorus oxides (Ag-VPO) as catalysts. ► Catalysts for allylic oxidation of cycloolefins. ► High enones yields of cycloolefins oxidations are achieved. ► It is a high yielding, safe and eco-friendly method.
