The current invention belongs to the technical fields of fine chemicals and related chemistry, and provides a preparation method for butadiene derivatives. Arylacetylenes and derivatives using as raw materials react in an anhydrous organic solvent in the presence of a metal catalyst and an additive, and are converted into 2,3-disubstituted-1,3-butadiene derivatives. The current invention has some beneficial characteristics such as cheap and readily available raw material, mild reaction conditions, environmentally friendly property and possibility of realizing industrialization, and obtains the 1,3-butadiene derivatives in high yields. The 1,3-butadiene derivatives synthesized by this method can be further functionalized into various compounds which have potential applications in development and research of natural products, functional materials and fine chemicals.
