| titleOfInvention | Preparation method of benzodithiol heterocyclic alkene skeleton compound |
| abstract | The invention discloses a preparation method of a benzodithiol heterocyclic alkene skeleton compound, which is prepared by reacting 2-bromothiobenzamide derivative with S 8 Adding the mixture into an organic solvent, adding a ligand and alkali, reacting in an inert atmosphere under the action of a copper catalyst, and then carrying out suction filtration and acidic hydrolysis treatment on a reaction system to obtain the catalyst. The method has the advantages of simple operation, easily obtained raw materials and reagents, mild conditions, green and environment-friendly reaction system and easy separation and purification of products, is suitable for synthesizing various benzodithiol heterocyclic alkene skeleton compounds, is particularly suitable for large-scale industrial production, can prepare the high-purity benzodithiol heterocyclic alkene skeleton compounds with high efficiency and high yield, and has the highest product yield of 91%. |
