The present invention provides a direct oxidation method for saturated hydrocarbon bonds in an organic compound. The method allows an organic compound with a saturated hydrocarbon bond to react with an oxidizing reagent in the presence of cerium complex under visible light irradiation, thus oxidizing the saturated hydrocarbon bond to afford an oxidation product. The present reaction only needs to be carried out at room temperature, while the reaction efficiency remains high. In addition, only visible light is required to provide the energy for activation, rendering the present strategy is a milder and greener reaction method. The cerium catalyst used in the method is low in cost, simple and efficient, while the oxidizing reagent used is also stable in nature and low in industrial cost, rendering the catalytic system highly practical. Furthermore, environmental pollution caused by heavy transition metals and peroxides can be avoided in such strategy.
