The invention discloses a preparation method of a sulfoxide type organic compound. The method is as follows: thioether used as reaction substrate and oxidant are used to perform oxidation reaction at the temperature ranging from the room temperature to 60-100 DEG C for 2-24 hours in the presence of catalyst to obtain sulfoxide, wherein the structural general formula of thioether in the reaction system is shown in the specification; R1 and R2 are same or different and are both selected from C6-C12 aryl or C6-C12 substituted aryl, C1-C15 alkyl or C1-C15 alkyl substituted by heteroatom and C2-C8 alkenyl; the catalyst is selected from one of cerium trifluoromethanesulfonate, cerium chloride heptahydrate, ammonium cerium nitrate, cerium nitrate hexahydrate and cerium (III) sulfate; and the oxidant is selected from one of oxygen, air and t-butylhydroperoxide. The method is green and mild and has high selectivity and wide application range. |
