| titleOfInvention | A kind of synthetic method of 4-cyclobutylbiphenyl fluorine-containing compound |
| abstract | The invention discloses a method for synthesizing 4-cyclobutylbiphenyl fluorine-containing compounds. The p-chlorohalobenzene is used as an initial raw material, and the Grignard reaction is carried out to generate it; the coupling reaction with cyclobutanone generates cyclobutanol chlorobenzene; and the dehydration reaction is carried out. Cyclobutene chlorobenzene is generated; 4-cyclobutenyl benzene boronic acid is generated by one-pot reaction; 4-cyclobutenyl biphenyl fluorine-containing compound is generated by coupling reaction with fluorine-containing halogenated benzene; 4-cyclobutenyl biphenyl is obtained by hydrogenation reaction The butyl biphenyl fluorine-containing compound IX has the characteristics of high conversion rate, low cost, safe and stable process, short reaction steps, green process route and less pollutant discharge. |
