Popis:	The reaction of olefins with cerium(IV) sulfate tetrahydrate [Ce(SO4)2·4H2O, CS] in acetone–H2O under reflux for 5 h gave 2-oxo- and 2-oxo-5-hydroxy derivatives. In this reaction, the yields of 2-oxo-5-hydroxy derivatives were dependent on the quantity of H2O. Moreover, the reaction of α, β-unsaturated ketones with CS in acetone–H2O yielded 2,7-dioxo-3-hydroxy or 3,8-dioxo-4-hydroxy derivatives. The reaction mechanism is also discussed.
