The oxidative olefination of sp(2) C-H bonds of anilides with both activated and unactivated alkenes using an (electron-deficient η(5) -cyclopentadienyl)rhodium(III) complex is reported. In contrast to reactions using this electron-deficient rhodium(III) catalyst, [Cp*RhCl2 ]2 showed no activity against olefination with unactivated alkenes. In addition, the deuterium kinetic isotope effect (DKIE) study revealed that the C-H bond cleavage step is thought to be the turnover-limiting step.
报道了使用（缺电子的η(5)-环戊二烯基）铑(III)配合物对酰胺的sp(2) C-H键与活化和未活化烯烃进行氧化烯基化反应。与使用这种缺电子铑(III)催化剂的反应不同，[Cp*RhCl2 ]2对未活化烯烃的烯基化反应没有活性。此外，氘动力学同位素效应（DKIE）研究表明，C-H键断裂步骤被认为是周转限制步骤。
