cyclopentadienyl (Cp)-Rh(III) complex, bearing ester and pendant amide moieties on the Cpring [CpARh(III)], is able to catalyze the aerobic oxidative olefination of benzamides, bearing nonspecial carbamoyl groups, with styrenes including disubstituted ones at relatively low temperature (60–80 °C). The presence of both the ester and pendant acidic N-phenylcarbamoyl moieties on the CpA ligand play important
已经确定,新开发的中等电子缺陷的环戊二烯基(Cp)-Rh(III)配合物在Cp环[Cp A Rh(III)]上带有酯和侧基酰胺部分,能够催化好氧氧化烯化反应带有非特殊氨基甲酰基基团的苯甲酰胺,在相对较低的温度(60–80°C)下含苯乙烯,包括二取代的苯甲酰胺。Cp A配体上的酯和酸性N-苯基氨基甲酰基侧基的存在在促进催化的过程中起着重要作用,同时又不影响配合物的热稳定性。

An attractive deoxygenative cross-coupling of amides with polyfluoroarenes was successfully achieved. Aromaticamides act as readily available carbene precursors through a Sm/SmI2-mediated deoxygenation process, and the insertion of the carbene into the C−H bond of polyfluoroarene affords architecturally complex and functionally diverse α-polyfluoroaryl amines in a single step.
and site-selective nitrate-promoted C–H bond fluorinationusing various weak coordinating amides as intrinsic directing groups was developed. Diverse tertiary and secondary amides underwent selective aromatic C–H bond fluorination, which features broad substrate scope, good regioselectivity, and mild conditions. Moreover, the late-stage C–H bond fluorination of the challenging benzeneacetamides via distal
