This study reports a Cs2CO3-promoted cross-coupling reaction of arenes with cyano-/nitro-substituted aryl halides in DMSO to afford biaryls in the absence of ligands. The cyano/nitro groups in biaryls are shown to be useful for further transformations. Additionally, the formation of dibenzofurans from reactions between arenes and 1-bromo-2-iodobenzene is reported. A radical mechanism for the formation of biaryls is proposed based on control experiments and theoretical studies.
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.
