Abstract

Conceptually different approach toward biaryl syntheses by photoinduced direct C–H arylation of benzene and thiophene in the presence of t-BuOK is reported. The reaction proceeds through photo-and base-promoted homolytic aromatic substitution. The o-, m-and p-substituted ArI, as well as the electron-donating and electron-withdrawing nature of the substituents were found be good to excellent substrates. Heteroaryl, ArBr, ArCl and ...
