Zinc or swim: Arylation of benzyl trifluoroacetates with arylzinc reagents in the presence of β-hydrogen atoms were realized under mild conditions. Both electron-rich and electron-deficient arene substrates were successfully arylated. This arylation method could offer a very versatile synthetic route to access a series of diversity-oriented diarylalkane motifs. TFA = trifluoroacetyl.
