  螯合辅助的Rh（I）催化的芳香族酮亚胺或酮与烯烃的邻烷基化。

  摘要：

  本文描述的是芳族酮亚胺或酮与烯烃的Rh（I）催化的邻烷基化。该方法对包括烯烃烯丙基质子，α，ω-二烯和内烯烃的1-烯烃在内的各种烯烃显示出高反应活性和对单烷基化的选择性。为了进行机理研究，进行了H / D交换实验，结果表明，即使在45°C的低温下，邻位CH键也很容易断裂。该反应的关键步骤是形成稳定的五元链通过螯合辅助邻位CH键活化的金属环。此外，通过添加50mol％的苄胺作为螯合辅助工具，成功实现了Rh（I）配合物与芳族酮的直接邻烷基化。

  reaction of the imine of aromatic ketones with functionalized alkenes was performed under a catalytic amount of (PPh3)3RhCl, and corresponding ortho-alkylated ketones were obtained after hydrolysis. A variety of functional groups in the alkene were tolerated in this ortho alkylation. This procedure expands the scope of ortho alkylation to the direct ortho functionalization of aromatic ketones.
