|Abstract:||Epoxidation of isolated and allylic olefins with dodeca-phosphotungstic acid, H<sub>3</sub>[PW<sub>12</sub>O<sub>4</sub>0]xH<sub>2</sub>O and urea hydrogen peroxide (UHP) adduct as an oxidant has successfully been carried out under homogenous conditions with the aid of isopropanol:water (4:1) as solvent, thereby avoiding the use of expensive phase transfer catalyst. The method has proven to be efficient in terms of percent yield, cost, reaction conditions and ease of work-up.|
