Oxidative coupling of primary, secondary, and tertiary benzamides with internal alkynes proceeds efficiently under rhodium catalysis to selectively give the corresponding 1:1 and 1:2 coupling products, accompanied by C–H and/or N–H bond cleavages. Some of the products exhibit intense fluorescence in the solid state.
synthesis, characterization, and catalytic performance of iridium(III) catalysts that bear an amide‐pendant cyclopentadienyl ligand ([CpAIrI2]2) is reported. These [CpAIrI2]2 catalysts were obtained from the complexation of a CpA ligand precursor with [Ir(cod)OAc]2 followed by oxidation. Double aromatic homologation reactions of benzamides with alkynes by fourfold C−Hactivation proceeded in good to high
