The invention belongs to the technical field of organic chemistry, and in particular relates to a phosphine-containing chitosan-supported palladium metal catalyst and a preparation method thereof. The present invention applies chemical synthesis means to compound compounds With palladium salt Pd (X) 2 derived from the reaction. After the phosphine-containing chitosan and palladium metal salt formed by the present invention form a catalyst, it can be used for the Suzuki coupling reaction of halogenated aromatic hydrocarbons and arylboronic acids, and has high catalytic activity and cyclability, and has practical value. |
