The invention relates to a method for catalyzing hydrosilylation reaction by using p-cymene ruthenium dichloride dimer, which comprises the following steps: taking p-cymene ruthenium dichloride dimer as a catalyst, and carrying out hydrosilylation reaction on hydrogen-containing siloxane and unsaturated hydrocarbon to obtain an alpha addition product. The invention can realize that one catalyst catalyzes a plurality of silicon-hydrogen addition reactions, and the catalyst has very good universality; compared with the traditional platinum catalyst, the ruthenium catalyst has the advantages of low cost, less side reaction of the catalytic reaction, high yield, short reaction time and high safety, and is suitable for industrial production. |
