-
Paragraph 0014, (2019/03/06)
The invention discloses a method for synthesizing tert-[...] biphenyl compounds, which belongs to the field of organic synthesis. In the oxygen free atmosphere, in order to di-tert-butylphenol [...] as raw material, under the action of the palladium catalyst, with the O-bromophenylacetic reaction, then the obtained by coupling with aryl boric acid di-tert-butylphenol [...] biphenyl compound. Compared with the prior art the invention less reaction steps, the operation is simple, high yield, is more suitable for industrial production. (by machine translation)

Bulky, electron-rich phosphine ligands with a biphenyl backbone, when combined with Pd(OAc)2, give highly active catalysts for the α-arylation of ketones. The ligand 2-methyl-2'-dicyclohexylphosphinobiphenyl is particularly effective, and with
