PROBLEM TO BE SOLVED: To provide a method for producing radicals that can generate (produce) radicals under a mild condition, and a method for producing oxidation reaction products using the method for producing radicals.SOLUTION: A method for producing radicals includes a mixing step for mixing at least one of a Lewis acid and a Broensted acid with a radical generation source. A method for producing oxidation reaction products is for producing oxidation reaction products by oxidizing an oxidation target, and includes a radical production step for producing radicals by the method for producing radicals, and an oxidation reaction step for generating the oxidation reaction products by the reaction between the oxidation target and an oxidant.SELECTED DRAWING: None
