A kind of synthetic method of chiral and achiral 2,2'-dihalogenated biaryl compounds |
| abstract |
The present invention provides a method for synthesizing chiral and achiral 2,2'-dihalogenated biaryl compounds (III). The synthesis method uses diaryl cyclic iodonium salts and cheap halogen salts as raw materials 2,2'-dihalogenated biarylation products are generated in the next step of the catalysis of copper salts by ring-opening reaction; the present invention has rich raw material sources, low cost, simple operation, high yield, and the synthesized products have various structures, Novel and widely applicable; |
