A controllable method for the functionalization of XantPhos Pd‐G3 precatalyst with thiosugars and thiols has been established. Under mild and operationally simple reaction conditions through just mixing of precatalyst and thiosugars (α‐ or β‐mono‐, di‐ and poly‐thiosugar derivatives) in water at 25 °C for 20 min, a series of 1‐aminobiphenyl thioglycosides that are difficult to synthesize by classical
A method for producing a biaryl compound, comprising reacting an aromatic organic compound with at least one compound selected from the group consisting of aromatic organoboron compounds and boroxine compounds, in the presence of a zero-valent nickel catalyst, phosphine ligand and base.
