    摘要: A process for preparing one or more carbazoles comprising (a) contacting one or more compounds represented by formula (1) below with diboron reagents in the presence of PdCl2(dppf) to form one or more 2,2′-dichlorobiaryl represented by formula (2) below; and (b) contacting the one or more 2,2′-dichlorobiaryls with one or more H2N—Y compounds, in the presence of one or more palladium containing catalytic components; thereby forming one or more carbazoles represented by formula (3) below is provided.
