Biaryl Formation via Base-Promoted Direct Coupling Reactions of Arenes with Aryl Halides.

ABSTRACT: In the absence of ligand, Cs₂CO₃-promoted cross-coupling reaction of arenes with cyano-/nitro-substituted aryl halides in DMSO affording biaryls is reported. The cyano/nitro group in biaryls is useful and convenient for further transformation. The formation of dibenzofurans resulting from the reactions between arenes and 1-bromo-2-iodobenzene is also reported. On the basis of control experiments and theoretical studies, a radical mechanism is proposed for the formation of biaryls.
