cyclopentadienyl (Cp)-Rh(III) complex, bearing ester and pendant amide moieties on the Cp ring [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。
