The invention relates to the field of organic synthesis and provides a synthesis method of a carbonate modified fluoride-free organic phosphine ligand. The synthesis method comprises the following steps: preparing a Grignard reagent from the raw material p-bromoanisole or derivative thereof; enabling the Grignard reagent to react with a phosphorus source to generate a skeleton structure molecule with triphenylphosphine; and performing oxidation, demethylation, nucleophilic substitution and reduction to obtain a target molecular structure. The synthesis method has the following effects and benefits: a novel carbon dioxide-philic organic phosphine ligand is synthesized, the solubility of the phosphine ligand in supercritical CO2 is increased, and application of a fluoride-free phosphine ligand organic metal catalyst in supercritical CO2 is realized. Moreover, the organic carbonate compound is insoluble in a weakly (non-) polar organic solvent (such as alkane compounds), the property enables a phase splitting function of the carbonate modified fluoride-free organic phosphine ligand in the reaction system, and the recycling and reusing of the catalyst are realized.
