Procedure

To a mechanically stirred solution of styrene (0.01 mol), dodecane (0.001 mol), urea (0.208 mol), potassium bicarbonate (0.003 mol) and manganese sulphate (0.1 mmol) in 10.0 ml of water at 30° C. is added 30% aqueous hydrogen peroxide (0.5 mol) in three equal portions over a period of 4 hours. After 5 hours the reaction mixture was extracted with 4×5 ml diethyl ether. The combined organic layer was dried over anhydrous sodium sulphate. Removal of solvent yielded styrene oxide in 90% yield with selectivity 90%.
