A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4020-99-9, Name is Methoxydiphenylphosphine, molecular formula is C13H13OP. In a Patent，once mentioned of 4020-99-9, Safety of Methoxydiphenylphosphine
The invention discloses a method for synthesizing thiophosphate compounds, the synthesis method of the reaction steps are as follows: the aryl disulfide is dissolved in a solvent, to the oxygen in air as the oxidizing agent, stirring at room temperature, by extraction, drying, filtering, silica gel column chromatography analysis process for purifying and reduced pressure distillation treatment to obtain the required thiophosphate compound. The thiophosphate compound is phosphorous acid three alkyl ester. The method under mild conditions and rapid and efficient one-step construction phosphorus – bond, the reaction relates to phosphorous acid three alkyl and aryl disulfide of the departure of the nucleophilic addition and alkoxy, the method of the invention is simple and efficient, but also can adapt to a wide range of the substrate, for preparing synthesis of the thiophosphate compounds provides a high-efficiency green method.
