    Rhodium-Catalyzed Alkylation of C–H Bonds in Aromatic Amides with Styrenes via Bidentate–Chelation Assistance

    No full text
    Rhodium-catalyzed alkylation reactions of aromatic C–H bonds in aromatic amides with styrene derivatives have been developed by using an 8-aminoquinoline as a bidentate directing group. C–C bond formation selectively occurred between the <i>ortho</i> C–H bonds in aromatic amides and the terminal carbon of the styrene derivatives. The presence of an 8-aminoquinoline moiety is essential for the success of the reaction

    Rh(I)-Catalyzed Alkylation of <i>ortho</i>-C–H Bonds in Aromatic Amides with Maleimides

    An alkylation of C–H bonds with maleimides by a rhodium-catalyzed reaction of aromatic amides containing an 8-aminoquinoline moiety as the directing group is reported. Various <i>N</i>-substituents in the maleimide, including methyl, ethyl, cyclohexyl, benzyl, and phenyl groups and even H, are applicable to the reaction. The reaction is highly regioselective at the less hindered <i>ortho</i>-C–H bond when <i>meta</i>-substituted aromatic amides are used as substrates
