A method for preparing a multi-substituted acrylic acid compound includes steps as follow. A reaction solution is provided, wherein the reaction solution includes an organometallic reagent, a nickel-containing metal catalyst, a catalyst ligand, a first solvent, and the organometallic reagent is a Grignard reagent or a Gilman reagent. An addition step is conducted, wherein an alkyne compound is mixed with the reaction solution so as to undergo an addition reaction, thus an intermediate solution is obtained. A substitution step is conducted, wherein a carbon dioxide is introduced into the intermediate solution so as to obtain the multi-substituted acrylic acid compound.
