The invention belongs to the field of fine chemicals and relevant chemical technologies and provides a preparation method of a butadiene derivative. The preparation method comprises the following steps of by taking phenylacetylene and a derivative thereof as raw materials, under the actions of a metal catalyst and an additive, performing reaction in an anhydrous organic solvent, and converting thephenylacetylene and the derivative thereof to a 2,3-di-substituted-1,3-butadiene compound. The preparation method has the beneficial effects of being simple and convenient to operate and mild in condition, being environmental friendly, having the possibility of realizing industrialization, and preparing the butadiene compound with a higher yield. The butadiene compound synthesized by utilizing the method can perform further functionalization to obtain various compounds, and then the compounds are applied to development and study of natural products, functional materials and the fine chemicals.
