| titleOfInvention | Preparation method of trans-stilbene compound |
| abstract | The invention relates to a method for synthesizing a trans-stilbene compound, which is characterized in that in a nitrogen or inert gas atmosphere and an organic solvent, tolane is used as a reaction substrate, and carbon-carbon triple bonds in a tolane structure are reduced by using elemental selenium and alkali through chemoselectivity to obtain the trans-stilbene compound. The diphenylacetylene used as the raw material is easy to synthesize; the simple substance selenium is cheap and easy to obtain. The method for synthesizing the trans-stilbene compound has the advantages of wide range of reaction substrates, good functional group tolerance, simple reaction conditions, high yield and high purity of products, develops a new synthesis route and method for the trans-stilbene compound, and has good application potential and research value. |
