Y. Kawamura et al., PALLADIUM-CATALYZED ARYLATION OF 2,6-DI-TERT-BUTYLPHENOL WITH ARYL BROMIDES TO PRODUCE 1,1'-BIPHENYL-4-OL DERIVATIVES, Chemistry Letters, (9), 1998, pp. 931-932
A sterically hindered phenol, 2,6-di-tert-butylphenol, efficiently rea
cts with various bromobenzenes in the presence of a palladium catalyst
and a base to selectively afford the corresponding 1,1'-biphenyl-4-ol
derivatives.
